Performance Table of O-ring Material O-ring is a commonly used sealing component, widely used in mechanical, automotive, aviation and other fields. Different application scenarios require the selection of different materials.   1. Fluororubber (FKM) Fluororubber has excellent oil resistance, heat resistance, and chemical corrosion resistance, making it suitable for sealing requirements in harsh environments such as high temperature, high pressure, and high speed. But the price is high and not suitable for low-cost applications. 2. Nitrile rubber (NBR) Nitrile rubber is a commonly used universal sealing material with good oil resistance, wear resistance, and aging resistance, suitable for sealing requirements at low temperatures, low pressures, and low speeds. But it is prone to hardening and aging in high temperature and high pressure environments. 3. chloroprene rubber (CR) Chloroprene rubber has good oil resistance, cold resistance, and weather resistance, and is suitable for sealing requirements at low temperatures, low pressures, and low speeds. But it is prone to aging in high temperature and high pressure environments. 4. Butyl rubber (BR) Butyl rubber has good elasticity and wear resistance, suitable for sealing requirements at low temperatures, low pressures, and low speeds. It may soften during high temperatures. 5. Ethylene propylene rubber (EPDM) Ethylene propylene rubber has excellent oxidation resistance, ozone resistance, and weather resistance, making it suitable for sealing requirements in outdoor environments. But it is prone to hardening in high temperature and high pressure environments.   The above are common O-ring materials and their characteristics. Choosing the appropriate material can improve the sealing effect and service life. If you are interested in or have any questions about the above O-rings, please click to contact us.

Aging is not fast: Unlike some sealing materials, rubber will gradually age naturally under pressure and reduce elasticity under any stress conditions. So seals actually have a certain service life, which is closely related to the quality of the sealing material. Due to the small pre compression amount after installation, the aging rate of the seal will be relatively slower. Good stability: determined by the shape and characteristics of the rectangular seal, it will not twist after installation; The deformation after pre compression is small; When the hydraulic pressure changes, the shaping is also relatively small. The cross-sectional stability of the seals is good. Good sealing performance: When using O-ring seals as end face seals, a "suction back effect" will occur when there are large pressure pulses. The first effect is generated by the pressure between the low-pressure side of the O-ring seal and the groove side in the groove. When pressure shock occurs, the fluid is discharged as the O-ring seal moves. When the pressure drops, a slight leakage similar to sweating occurs. When using rectangular seals, due to their geometric characteristics, there will be no sweating issues. Strong anti extrusion performance: When using O-ring seals, under frequent or long-term pressure shocks, over time, a small amount of sealing material will be sheared and extruded from the low-pressure side gap. This phenomenon is called "extrusion damage". Under the same operating conditions, if rectangular seals are used, there will be no "extrusion damage". High sealing pressure: The working pressure of O-ring seals is 32MPa, and the working pressure of rectangular seals is 50MPa. When O-ring seals are used for radial sealing and the pressure exceeds 10MPa, a retaining ring needs to be added on the low-pressure side to prevent damage caused by extrusion. When using rectangular seals, there is no need to set up a retaining ring.  

How to choose the appropriate material for customizing silicone products? In the field of silicone product customization, material selection is a key factor determining product quality and performance. The appropriate silicone material not only meets the functional requirements of the product, but also ensures safety and comfort during use.   Silicone materials can be roughly divided into the following categories based on their properties and applications: 1. Divided by performance Ordinary silicone: It is the most common silicone material with excellent weather resistance, high temperature resistance, corrosion resistance, and other characteristics. Suitable for general industrial products such as seals, buttons, etc., with relatively low cost, but not suitable for direct contact with food or medical use. Food grade silicone: Complies with international food safety standards such as FDA and LFGB, is non-toxic and harmless, and can be used to make silicone products that come into direct contact with food such as tableware, kitchenware, and baby pacifiers. Stable within the range of -20 ℃ to 200 ℃, it can withstand high temperature steaming and disinfection, as well as be used for frozen dough operations. It achieves a 99.9% antibacterial rate through physical adsorption and can inhibit mold growth without the need for chemical coatings. Medical grade silicone: It has higher requirements than food grade silicone and requires medical grade certification such as ISO10993. It is used for the production of medical devices, human implants, etc. It has strict requirements for biocompatibility and sterility. High strength silicone: It has high tensile strength and wear resistance, and can withstand high pressure and friction. It is suitable for silicone products that can withstand high pressure and friction, such as industrial products, sports equipment, etc. Special performance silicone: designed according to specific requirements, such as conductive silicone used for sealing and conductive connections in electronic products, and flame-retardant silicone used for occasions requiring fire safety. Divided by physical state Solid silicone: mainly used for molded products, such as silicone sleeves, silicone tableware, silicone buttons, etc. Shaped by mechanical high-temperature extrusion, generally divided into silicone strips, silicone tubes, etc., with a hardness of around -10 degrees to 40 degrees. Liquid silicone: mainly used for extruded products such as silicone nipples, silicone tubes, etc. Its material is relatively soft and mainly used in medical technology, human organs, and other fields.   2. Basis for selecting silicone material When choosing silicone material, the following factors need to be considered comprehensively: Application scenarios Temperature resistance range: Select the appropriate silicone type based on the temperature range of the product's usage environment. For example, products working in high-temperature environments should use high-temperature resistant silicone gel; For products used in frozen environments, it is necessary to choose silicone materials that can maintain good elasticity at low temperatures. Contact medium: If the product needs to come into direct contact with food, drugs, or the human body, food grade or medical grade silicone must be selected to ensure the safety and non toxicity of the product. Physical properties: Select the appropriate silicone formula based on the physical properties requirements such as hardness, tensile strength, and tear strength of the product. For example, for products that require significant pressure and friction, high-strength silicone should be chosen; For products that require a soft touch and good elasticity, low hardness silicone can be chosen. Special performance: If special properties such as conductivity, flame retardancy, and anti-static are required, corresponding special performance silicone gel should be selected. Product characteristics Dimensional accuracy: The dimensional accuracy of silicone products is very important and must be accurately measured and customized according to the actual size of the product. Sizes that are too large or too small can cause silicone products to not fit tightly to the product, affecting their effectiveness. Therefore, when choosing silicone material, its processing performance and dimensional stability need to be considered. Thickness and hardness: The thickness and hardness of silicone products should be selected based on the characteristics and usage requirements of the product. Thin silicone products may not provide sufficient protection, while thick silicone products may affect the tactile feel of the product. In terms of hardness, silicone products that are too soft may be prone to deformation, while silicone products that are too hard may not be comfortable enough. Cost and Environmental Protection Cost control: Reasonably control costs and avoid unnecessary waste while ensuring product quality. The price of silicone varies greatly among different materials, and it is necessary to choose the appropriate material based on the product budget and market demand. Environmental friendliness: Ensure that the silicone material used complies with relevant environmental standards and does not contain harmful substances. With the increasing attention of consumers to environmental issues, choosing environmentally friendly silicone materials has become a trend.   3. Material selection for common application scenarios Food contact field In the field of food contact, such as making tableware, kitchenware, baby pacifiers, etc., food grade silicone must be used. This type of silicone meets strict food safety standards, ensuring that it does not release harmful substances that pose a threat to human health during long-term use. For example, some high-end food grade silicone pad panels use platinum silicone or liquid silicone, with a silicon dioxide content of over 98%, which remains stable in the range of -20 ℃ to 200 ℃. They can withstand high temperature steaming and disinfection, as well as be used for frozen dough operations. Medical field In the medical field, such as the production of medical devices, human implants, etc., medical grade silicone should be used. Medical grade silicone has extremely high biocompatibility and non toxicity, which can meet the high standard requirements in the medical field. The production process requires strict testing and certification to ensure the safety and reliability of the product. Industrial sector In the industrial field, such as making seals, pipelines, etc., ordinary silicone or high-strength silicone can be selected according to specific usage environments and requirements. Ordinary silicone has stable performance, relatively low price, and is suitable for general industrial environments; High strength silicone has high tensile strength and wear resistance, and can withstand significant pressure and friction, making it suitable for industrial scenarios that require high product performance. In the field of electronic products In the field of electronic products, such as making sealing and conductive connecting components for electronic products, conductive silicone can be used. Conductive silicone has good conductivity and sealing performance, which can effectively protect electronic products from external environmental interference and damage.   Choosing the appropriate silicone product material for customization is a process that comprehensively considers various factors such as application scenarios, performance requirements, and cost budgets. By deeply understanding the basic characteristics and material classification of silicone, combined with specific application scenarios and product features, making scientific and reasonable choices can not only enhance the market competitiveness of the product, but also better ensure the safety and experience of users.

The role of desiccants can be seen everywhere in daily life, and their presence can be seen in almost any new product packaging. Although we have seen the widespread use of silicone desiccants, how long can they be stored, and can long-term storage really prevent moisture and mold? Will there really be no expiration phenomenon?   Firstly, we understand that since desiccants are designed to prevent moisture and mold, the material must have high activity adsorption capacity, a certain degree of acid-base reaction, slow aging rate, insolubility, strong chemical stability, and other advantages in order to be stored for a long time. Silicone materials belong to high activity adsorption materials, which cannot tolerate any substances and have strong adsorption capacity. They mainly adsorb water vapor by adsorption method. Silicone materials have strong stability and can be stored for a long time without any aging or deterioration phenomenon, so their effectiveness and lifespan as desiccants are completely stable. In the service life of silica gel desiccant, experimental methods can be adopted. If it can be stored for a long time in a dry and liquid free environment and has a certain moisture-proof and mildew proof effect, if it is used in a high humidity and severe ozone environment, the service life will be reduced. In the case of water seepage, it can be used for about 1 year. If it does not leak water, it can be used for a long time. Its service life is determined by the environment, but it can be used for a long time if it is stored normally. The use of desiccants is widely used in various industries, and this type of auxiliary material has also made desiccant materials a category of production conversion in the manufacturing industry. Desiccant materials can also be divided into many types, including mineral desiccants, fiber desiccants, quicklime materials, montmorillonite desiccants, activated alumina, and silica gel desiccants. Currently, silica gel desiccants are one of the most commonly used types, and they are basically stationary items that no one can move at will. They can still achieve good results in moisture and mold prevention!

Font stacking printing on various craft products has a role, and silicone products are no exception. For lettering printing, most products are influenced by brand names and company logos, which mainly target appearance components. However, when customizing logos, one does not know their own needs and cannot describe the desired effect. Therefore, for silicone appearance lettering, let me briefly introduce the common processing methods of silicone product lettering technology!   Mold logo engraving is currently the most basic way of logo production, which is simple and clear with consistent concave and convex shapes. The main process is to wash out the empty space of the mold logo in the upper and lower molds during mold processing. If the logo needs to protrude, the position is dug out in the upper mold, and if it needs to be concave, the position is dug out in the lower mold. When the raw materials are placed, the product is filled in the logo area and vulcanized to form the desired logo shape. For example, if other logo colors are needed, the K position needs to be dug out in the mold core, and the logo needs to be separately vulcanized and placed in the main mold to make a color separated logo and obtain a two-color product.   Printing logos, in the early days of the printing industry, seemed to be a relatively niche industry. Some people were worried that the ink would fall off after prolonged use, and the effect of the printing screen could not be achieved. However, now that the technology in China's printing industry has matured, if you do not want a three-dimensional effect, you can choose to use the printing brush form. Currently, the printing industry is very popular, and it will not fall off after printing is completed. The clarity of the screen is already very precise, which completely improves the quality and effect that consumers are worried about!   Pad printing and color printing are mainly used to produce LOGO patterns of different colors and multiple colors. This method can be processed through several methods such as heat transfer printing and water transfer printing, which are complex and inefficient. However, the LOGO effect of the product may not disappoint you. Generally, excess silicone jewelry and multi-color silicone products are more commonly used. There are many processing methods for silicone products, and there is nothing you can't think of that can't be achieved. In addition, there are also many other logo processing methods, such as glue dripping, coating, sewing, and so on.

In modern industrial products, many basic things cannot be separated from the processing of molds. Many materials we see in daily life, such as hardware, plastic, silicone, and other punching materials, are made using different molds. Therefore, compared to many industry professionals, the importance of molds should be known. Similarly, in the silicone industry, it is no exception. Without molds and auxiliary tools, it is impossible to complete many of our products.   In the silicone product industry, molds are the key to the entire product, and all products must be produced using molds to meet the requirements. However, silicone is different from plastic and hardware grinding tools in that it can be molded for sample making, which makes many people puzzled whether to use 3D printing or directly use production molds for sampling. Today, we will explain the different processes and methods of molds. Due to the fact that silicone product materials belong to soft colloids and are not processed using hard adhesives, 3D printing is a drawback. However, with the maturity of 3D printing, the use of soft adhesives is gradually becoming more mature. However, the material and workmanship of 3D printed soft adhesives still cannot achieve the desired effect and texture of the finished product. While the structure alone is not a problem, the effect still needs to be evaluated through the production of molds and the processing of finished products. The bulk mold and sample mold are the processes we need to go through. Many customers' silicone accessories cannot meet the requirements in terms of assembly and appearance, and they dare not rashly open production bulk molds. Otherwise, they are worried that the structure of the mold will not be correct after opening, and the appearance effect will not meet the requirements, resulting in poor quality of the silicone product and difficult project progress. Therefore, in the early stage of production, in order to meet the customer's appearance and structure requirements and achieve a similar fitting effect, we need to open a small mold and create a sample mold for comparison. After achieving the desired effect, we can proceed with the production of bulk molds. The difference between the production mold and the large goods mold is that the large goods mold can produce many points in a the first mock examination, which can be more efficient in production and processing in mass production. The sample mold is used for the qualification requirements of experimental samples in the early stage. Their difference is that one is only used for sample making experiments, and the other is used for mass production of large goods. So many friends do not understand why it is not possible to directly use sample molds for mold production.

With the promotion and application of silicone products in daily life, more and more industries are using silicone as the main material for customized processing of product categories. However, many consumers are troubled by the defects and problems brought by different silicone materials and usage areas. One of the reasons is that the surface of silicone products turns white after stretching. Under what circumstances will the product appear whiter?   It is normal for silicone rubber products to turn white after stretching and twisting, but it may mislead some friends into thinking that turning white is a bad phenomenon. Why does the product turn white? Firstly, the raw material of silicone belongs to semi transparent white mist material, so the whitening of the product after stretching is mainly related to the raw material. Silicone materials are mainly divided into ordinary silicone, gas-phase silicone, medical silicone, and special silicone, and different grades of materials can be seen from stretching. The main factor causing the product to turn white is that it belongs to precipitated silicone rubber, and the material is mainly precipitated silica. This type of silica is mainly made from industrial water glass obtained by reacting quartz sand and soda ash at high temperatures, and is prepared into a dilute solution with water. After adding the compound precipitate under epoxy conditions, wash, dry, and crush to obtain precipitated silica. So the blurriness of its products is mainly due to the presence of a certain compound in the silicon molecular chain, which causes whitening during stretching. In addition to precipitated silica gel, there is also gas-phase silica gel, which is more prominent than precipitated silica gel. That is what we often refer to as food grade silicone material. It has higher purity and stronger molecular structure. It is made of silicon tetrachloride and gas fired silica, with a molecular fineness of up to 800-1000 mesh for silicon, while the molecular fineness of ordinary precipitated silica gel is about 400-600 mesh. However, gas-phase silicone does not appear white or foggy when stretched. So sometimes when we distinguish silicone, we can distinguish whether it belongs to ordinary silicone or food grade silicone. Generally, ordinary silicone gel undergoes fogging during molding and vulcanization by silicone rubber product manufacturers, while gas-phase silicone gel has superior performance, high raw material purity, and no whitening phenomenon during stretching and rebound.

In today's increasingly environmentally conscious world, environmental friendliness has become an important consideration when choosing materials. Who is better on the environmental track than PVC and silicone, two common materials? Today we will give you a deep analysis.   1. Analysis of the Environmental Protection Status of PVC. PVC, also known as polyvinyl chloride, is widely used in industry and daily life, such as plastic pipes, doors and windows, and wire sheaths. But its environmental issues cannot be ignored. During the production process, PVC requires the addition of plasticizers, stabilizers, and other additives. Some plasticizers, such as phthalates, have been shown to have a disruptive effect on the human endocrine system and may pose a health hazard. Moreover, PVC contains chlorine, which releases harmful gases such as hydrogen chloride during combustion, polluting the air and corroding equipment; Abandoned PVC products degrade slowly in the natural environment and may release harmful substances into soil and water bodies, affecting ecological balance.   2. The environmental advantages of silicone are fully demonstrated. The main components of silicone are silicon dioxide and organic silicon polymers, which have stable chemical properties and are non-toxic and odorless. It has passed ROHS certification, which means it does not contain harmful heavy metals such as lead, mercury, cadmium, etc. The production process of silicone is environmentally friendly, and the curing process does not produce toxic by-products, without the need to add harmful additives. From a usage perspective, it is resistant to high and low temperatures and will not decompose or release harmful substances even at extreme temperatures ranging from -60 ℃ to 250 ℃, ensuring high safety. Widely used in food contact and medical fields, such as silicone kitchenware, baby pacifiers, medical catheters, etc. After disposal, silicone can be recycled and reused, reducing resource waste and landfill waste; Even if naturally degraded, it will not produce harmful substances and is environmentally friendly.   If you are looking for environmentally friendly materials and pursuing a green and healthy lifestyle and production method, in most cases, silicone is the better choice. In the current emphasis on environmental protection, choosing more environmentally friendly materials is your contribution to the sustainable development of the earth.

Silicone and PVC (polyvinyl chloride) are widely used polymer materials in modern industry and daily life. From electronic product casings to household items, from medical equipment accessories to children's toys, their presence can be seen everywhere. However, despite both possessing a certain degree of flexibility and plasticity, they have many essential differences. A deeper understanding of the difference between silicone and PVC not only helps professionals make precise decisions on material selection, but also enables ordinary consumers to have a better understanding when choosing products. From the perspective of composition and basic characteristics, silicone is a highly active and environmentally friendly material, mainly composed of silicon dioxide. Its unique open porous structure endows it with excellent adsorption performance and high stability. Its chemical properties are stable, and it hardly reacts with any substance except strong alkali and hydrofluoric acid; PVC is polyvinyl chloride, which is polymerized by ethylene monomer under the action of initiators. It is a thermoplastic with low cost, good flame resistance, insulation and chemical stability. In terms of physical properties, silicone gel is soft and has a delicate touch, excellent flexibility and elasticity, good resilience, and can withstand multiple bends without deformation; PVC has a wide range of adjustable hardness, and can be transformed from a hard material to a soft material by adding plasticizers. However, even if adjusted to a soft material, its softness and elasticity are difficult to compare with silicone, and PVC has a relatively rough hand feel. For example, touching silicone kitchenware and PVC plastic products with your hands can clearly feel the softness and skin friendliness of silicone and the stiffness of PVC. In terms of chemical properties, silicone has strong resistance to ultraviolet radiation and can maintain stability even when exposed to sunlight for a long time; Outstanding high temperature resistance, capable of withstanding temperatures of around 300 ℃ without producing harmful substances in high-temperature environments. It can be used to make baking molds and other products that come into contact with high-temperature food. PVC has good chemical stability and can resist the erosion of many common chemicals, but its high temperature resistance is poor. It may start to deform at around 70 ℃ and may release harmful gases at high temperatures, making it unsuitable for high-temperature environments. In terms of quality control, Dibo Silicone has established a sound quality management and testing system, strictly controlling every link from raw material procurement, production process to finished product inspection to ensure that product quality meets high standards. At the same time, we focus on customer service, providing timely, efficient, and professional pre-sales, in sales, and after-sales services, tailoring solutions for customers, and providing technical support. With high-quality products and services, we have won the trust of many customers. Our products are not only popular in China, but also exported to Europe, America, Southeast Asia and other places. In summary, there are significant differences between silicone and PVC in terms of composition structure, physical and chemical properties, processing applications, and environmental safety. When selecting materials in practice, it is necessary to comprehensively consider factors such as specific usage scenarios, performance requirements, cost budgets, and environmental standards in order to make the most of them and achieve the best results.

In daily life and industrial applications, anti slip performance is a key consideration for many material choices. Silicone and rubber, as two common polymer materials, are often used in anti slip scenarios due to their good flexibility and grip. So, silicone anti slip or rubber anti slip?The answer to this question is not absolute and requires in-depth analysis from multiple dimensions.   From the perspective of material properties, rubber and silicone have their own anti slip principles. The molecular structure of rubber gives it a high coefficient of friction on its surface, especially natural rubber and some synthetic rubber, which have a soft and elastic texture and can tightly adhere to the contact surface. In dry environments, rubber can provide excellent anti slip effect. For example, traditional rubber soles are designed with complex patterns to enhance friction with the ground, effectively preventing slipping. However, in special environments such as humidity and oil stains, the anti slip performance of rubber will significantly decrease. When it comes into contact with water, the surface is prone to become wet and slippery. Long term exposure to grease may also cause swelling, leading to changes in physical properties. In contrast, silicone exhibits unique anti slip advantages. The molecular structure of silicone is stable, and its surface has a certain degree of hydrophilicity. Even in humid environments, it can form a tight adsorption force with the contact surface. At the same time, silicone material itself is insoluble in oil and grease, and can still maintain good anti slip performance in oily environments. In addition, the surface microstructure of silicone can be optimized through special processes, such as adding concave convex textures and micro nano level rough surfaces, to further enhance friction. Experimental data shows that the specially treated silicone material has a friction coefficient on wet glass surfaces that is more than 30% higher than that of ordinary rubber, and its anti slip performance is particularly outstanding in extreme environments.   In the practical application of anti slip materials, Dibo silicone has demonstrated strong technical strength and innovation capability. Dibo silicone can customize the anti slip performance of silicone according to different usage scenarios through self-developed surface treatment technology. For example, for bathroom anti slip pad products, DiBo silicone adopts a three-dimensional honeycomb texture design, combined with micro nano rough surface treatment, so that the anti slip pad can firmly adhere to wet ceramic tile surfaces, effectively preventing slip accidents. In the industrial field, DiBo customizes anti slip silicone components for mechanical equipment. Through a special chemical cross-linking process, the bonding strength between the material and different materials such as metal and plastic is enhanced, and the surface friction is optimized to ensure stability and reliability under complex working conditions such as high temperature and oil pollution. Whether it is silicone or rubber, their anti slip performance is closely related to the design and manufacturing process of the product. By optimizing surface texture and adding special anti slip particles, the anti slip effect can be further improved. Therefore, when choosing anti slip materials, in addition to considering the characteristics of silicone and rubber themselves, attention should also be paid to the specific design and usage scenarios of the product, and a comprehensive judgment should be made in order to select the most suitable anti slip product for safety protection.
