Silicone O-ring is a common sealing component mainly used for sealing mechanical equipment. Considering that mechanical equipment needs to withstand the erosion of various lubricants and industrial lubricants during use, can silicone O-rings provide good sealing when facing these lubricants and oils? Let's analyze it below. Firstly, we need to understand the material characteristics of silicone O-rings. Silicone has excellent elasticity, high temperature resistance, and cold resistance, and can be used over a wide temperature range. Additionally, silicone has good oil resistance. However, the tolerance of different types of silicone materials to oily liquids varies. For the common lubricating oils and lubricants in mechanical equipment, we need to choose silicone O-rings with better oil resistance. Secondly, in addition to the material properties of silicone O-rings, the usage environment is another key factor affecting their oil resistance performance. If silicone O-rings are used in high-temperature environments, aging and hardening may occur over long-term use, thereby reducing oil resistance. So, for mechanical equipment in high-temperature environments, we need to choose silicone O-rings that have better high-temperature resistance characteristics. Finally, it is important to note the usage of silicone O-rings. If used improperly, silicone O-rings are easily damaged or aged. For example, when installing silicone O-rings, it is necessary to avoid scratches, clean the installation position before installation, and use the pressing method for installation. For long-term operating equipment, we also need to regularly inspect and replace silicone O-rings. In summary, silicone O-rings have good oil resistance to a certain extent, but in practical use, various factors such as material characteristics, usage environment, and application methods need to be considered. Therefore, when selecting and using silicone O-rings, it is recommended to choose according to the specific equipment situation and follow the correct installation and maintenance methods to ensure their good sealing effect.

In the silicone products industry, many silicone products not only have various shapes, but also have very different textures. Therefore, different silicone products can choose different processing procedures. In addition to molds, some products that have already been formed by silicone also require some surface treatment, such as baking, screen printing, oil spraying, etc. Do you know about the post-processing of these silicone products? Today, the editor will introduce to you why oil spraying is necessary in the production process of silicone products? At this point, many customers may not understand because when choosing silicone products, they need to have a good appearance and feel, a short delivery time, and a low price, which makes it difficult for some small silicone product processing factories. However, Honglin Silicone can achieve this by using the oil spraying process to improve the appearance quality and feel of the product, so that the received goods can maintain a good feel, and consumers can also get a better customer experience. So what are the oil spraying processes for silicone products? The oil spraying process can spray different inks on different products, such as matte surfaces, PU, Hand feel oil, etc. And the most common one is extinction, which is mainly used to spray a layer of matte ink on the surface of silicone products that does not affect the color of the product, to increase the feel of the product. The smooth and delicate mixed feel can better maintain the frosted effect of the product's appearance, which is different from products without oil spray. Secondly, PU is also a commonly used ink by silicone product manufacturers, mainly used in silicone buttons and some silicone jewelry daily necessities, with strong adhesion, good wear resistance, high transparency, and also enhances the feel effect of the product, enhancing customers' experience of the product.

As is well known, silicone has become the preferred material in fields such as kitchen and home furnishings, electronic appliances, and automotive vehicles due to its excellent properties of high temperature resistance, low temperature resistance, and chemical stability. Its key is its high temperature resistance performance. The high temperature resistance of silicone comes from its unique molecular structure of polydimethylsiloxane. The Si-O-Si bond energy of the main chain is much higher than that of the C-C bond of ordinary rubber, and its thermal stability is extremely strong. Secondly, the molecular chain has flexibility and forms a protective effect by connecting with organic side groups, making it difficult to decompose and deform in high temperature environments, and able to maintain good elasticity for a long time.From the perspective of temperature resistance, silicone can be divided into multiple grades. Conventional silicone can be used for a long time at temperatures ranging from -60 ℃ to 200 ℃, and can withstand high temperatures of up to 250 ℃ in the short term. Modified high-temperature silicone can meet the needs of general scenarios such as daily kitchen utensils and ordinary seals. Its long-term temperature resistance can be increased to 200 ℃ to 250 ℃, and it can reach 300 ℃ in the short term. It is suitable for industrial scenarios such as automotive engines and high-temperature steam equipment. Special high-temperature silicone can be modified with benzene, fluorosilicone, or filled with ceramics. Its long-term temperature resistance can reach 250 ℃ to 300 ℃, and its short-term peak can even exceed 350 ℃. It can cope with extreme high-temperature conditions such as aerospace and firefighting equipment. In addition, the actual temperature resistance of silicone is also affected by the purity of raw materials, production process, and usage environment. It is worth mentioning that high-quality silicone can be further improved in temperature stability through secondary vulcanization process, reducing deformation and odor problems at high temperatures. Overall, the temperature resistance of silicone materials is not limited to a single temperature range, but can cover various scenarios from daily to extreme.

The softness and hardness of silicone products directly determine their sealing effect, tactile comfort, and compressive strength. Whether it is the need for extremely soft maternal and child products or the requirement for high hardness industrial seals, precise control of hardness is the core challenge in production. Formula design: the underlying logic for regulating hardnessThe softness and hardness of silicone products first depend on the formula design of the base material. The type of base polymer determines the initial range of hardness, while the ratio of filler to plasticizer is the key to fine-tuning. Adding inorganic fillers such as gas-phase white carbon black can effectively fill molecular gaps, restrict molecular chain movement, and significantly improve hardness and modulus; On the contrary, if it is necessary to reduce hardness, it can be achieved by adding an appropriate amount of plasticizers such as silicone oil. For example, adding 10% silicone oil to liquid silicone can reduce its hardness by approximately 2 to 5 degrees. However, it should be noted that excessive addition of silicone oil can damage the molecular weight, leading to a decrease in tear resistance and even frost spraying. Therefore, scientific proportioning must be carried out while ensuring physical properties. Blending and compounding: a clever way to quickly respond to non-standard demandsIn actual production, customers often request non-standard special hardness requirements (such as 45 degrees or 55 degrees). At this point, directly mixing raw rubber materials of different hardness in proportion is an efficient and economical solution. For example, mixing 50 degree silicone with 70 degree silicone in a 1:1 ratio theoretically yields a rubber material of approximately 60 degrees. This method is widely used in sampling or small batch non-standard orders, which can significantly reduce inventory models. However, Weishun Silicone reminds that after mixing, it is necessary to fully thin and test the vulcanization curve, and the tensile strength of the blended material may be slightly lower than that of the raw material. Products with high performance requirements should be used with caution. Sulfurization process and post-treatment: a crucial step in determining final performanceIn addition to the formula, the influence of vulcanization process on hardness cannot be ignored. The three elements of vulcanization temperature, time, and pressure need to be accurately matched. Appropriately increasing the vulcanization temperature or prolonging the vulcanization time can accelerate the crosslinking reaction rate and increase the hardness by 1 to 2 degrees Celsius; However, if the temperature is too high or the time is too long, it can lead to excessive vulcanization, making the product brittle. In addition, secondary vulcanization (heat treatment) is also an effective means of adjusting hardness. By extending the treatment time at a specific temperature, the molecular structure of silicone can be further crosslinked, thereby stabilizing and improving the overall hardness. The control of the softness and hardness of silicone products is a systematic engineering involving material science and process optimization.

Silicone plugs are a common small-sized accessory that also plays a significant role. Therefore, they cannot be said to have little effect, as their presence does help us solve some of the problems of tightness, blockage, dust and water resistance, especially in industrial products, electronic appliances and other products. The role and material properties of silicone plugs are important. Silicone plugs, most people think of silicone rubber plugs, and now silicone rubber plugs account for the majority of the market share, while other rubber types choose more silicone plugs. Therefore, for soft rubber plug products, silicone and rubber materials can be considered a way of comparing and using them in various industries, which exposes many questions. Which is better, silicone plugs or rubber plugs?Today we are going to popularize, where are their differences? First, let's take a look at the rubber plug products. They are common in our industrial products and have strong advantages, such as dust and water resistance, wear resistance, tear resistance, aging resistance, oil seal resistance, and ozone radiation. The rubber plug materials are divided into several types. The materials there can be combined by dozens of materials. Therefore, according to different needs, the rubber plug with different characteristics, such as some mechanical seals, electronic seals, transportation vehicles, and even aerospace and military industries, is most suitable.Silicone plugs are completely different. Their materials are mainly environmentally friendly, textured, and comfortable to use, so they are used in some electronic products, daily necessities, and small-scale waterproof electronic appliances. Their raw materials are made by mixing precipitation method silicone with high particle molecules, silicone gum and white carbon black. The product's molecular chain is commendable, the material is soft, and the use is comfortable! Silicone rubber plugs and rubber plugs have one thing in common, both of which can be molded in the vulcanizing machine of silicone product manufacturers. However, the difference is that they are environmentally friendly, have good resistance to high and low temperatures, have a better feeling of color when touched, and can be in contact with human skin for a long time. Therefore, their electronic headphone rubber plugs, medical rubber plugs, and even rubber plugs in food products are widely used, mainly due to the special characteristics of the material that enable their range of use.Compared with silicone rubber, the material of silicone rubber can be compared to the application of new technologies in traditional industries. Silicone rubber materials have been heard of by people in the early days, so the use of silicone rubber materials is everywhere. Nowadays, more and more silicone rubber products are reused because of their stronger substitutability, environmental performance, and various technologies, such as shape, color, etc.

Silicone products are widely used in our daily lives, among which silicone kitchenware, silicone gifts, and silicone daily necessities are currently popular silicone products worldwide. With the increasing popularity of silicone products, consumers' demands for silicone products are becoming more personalized.The silicone products that are self molded have gained the favor of most consumers in the market because they are different from the general public, and their sales and profits are higher than those of public molded products. But what should be paid attention to in the production of silicone product molds?Customer1. Silicone product manufacturers not only need mold design capabilities, but also experienced mold designers, as experienced designers can avoid many misunderstandings, save time and costs, and improve production efficiency.2.

Silicone release agent is an indispensable auxiliary material in the production of silicone products, which can effectively reduce the adhesion between molds and products and ensure the quality of product molding. Different types of silicone release agents are suitable for different scenarios and have their own characteristics in terms of usage. When selecting, it is necessary to consider production needs and mold conditions. The following are the usage methods and characteristics of common silicone release agents: Material and Type1. Solvent based release agent: using organic solvents as carriers, containing effective ingredients such as silicone oil and wax, suitable for most silicone molds, especially for demolding complex shaped products.2. Water based release agent: Using water as a carrier, it has good environmental friendliness, low odor, and is friendly to operators and the environment. It is commonly used in production scenarios with high environmental requirements.3. Solvent free release agent: It does not contain solvents and exists directly in solid or paste form. It needs to be uniformly attached to the surface of the mold by heating or applying tools, and is suitable for high-temperature molding processes.Basic usage steps (general process)1. Mold pretreatment: Before demolding, the surface of the mold needs to be thoroughly cleaned to remove residual silicone debris, oil stains, dust, and other impurities. Special mold cleaning agents or alcohol can be used to wipe the mold surface to ensure it is dry and smooth, and to avoid impurities affecting the adhesion effect of the release agent.2. Selection and dilution of release agent (if necessary): Select the appropriate type of release agent based on the material of the silicone product, the complexity of the mold, and the production process. Partial solvent based or water-based release agents need to be diluted according to the instructions to avoid excessive concentration causing oil stains on the surface of the product, or low concentration affecting the release effect. 3. Uniform application: Manual application: Use a brush, sponge, or cloth dipped in release agent to evenly apply it to all surfaces of the mold cavity, including corners, grooves, and other details, ensuring no omissions or accumulation. Spray coating method: For large-area molds or mass production, a spray gun can be used to atomize the release agent and evenly spray it, paying attention to controlling the spraying distance (usually 30-50 centimeters) to avoid local excess.4. Drying and curing: After application, wait for the release agent to fully dry. Solvent based release agents generally need to be naturally dried or evaporated with hot air (avoiding direct exposure to high temperatures on the mold); Water based release agents can promote water evaporation through ventilation or low-temperature drying; The solvent-free release agent needs to wait for it to form a uniform film on the surface of the mold.5. Reuse and touch up: After a single demolding, if there is insufficient residual release agent on the surface of the mold, it should be promptly touch up. During continuous production, it is recommended to check the demolding effect every 3-5 molds, and decide whether to reapply based on the smoothness of demolding to avoid mold damage caused by ineffective demolding agents. Special precautions for different types of release agents1. Solvent based release agent: When using, it should be operated in a well ventilated environment, away from sources of fire, to avoid safety hazards caused by organic solvent volatilization; Operators are required to wear protective gloves and masks to reduce the risk of skin contact and inhalation.2. Water based release agent: After application, ensure that the mold is completely dry before pouring silicone, otherwise it may cause bubbles or pinholes on the surface of the product; If there is rust or oxide layer on the surface of the mold, it needs to be derusted first, otherwise the release agent is difficult to adhere.3. Solvent free release agent: The paste like release agent needs to be evenly scraped with a special tool (such as a scraper) to avoid uneven thickness; When forming at high temperatures, it is necessary to choose high-temperature resistant models to prevent the release agent from decomposing and failing at high temperatures.Effect judgment and adjustmentIf the surface of the product after demolding is smooth and flawless, the edges are intact, and there is no residual silicone in the mold, it indicates that the demolding agent is used correctly; If the product sticks to the mold, has surface scratches, or has excessive mold residue, it may be due to uneven application of release agent, incomplete drying, or improper selection of type. The mold needs to be cleaned again and the usage method adjusted. If pursuing efficient demolding, adapting to complex molds, and accepting the operating standards of solvent based products, solvent based demolding agents are a reliable choice; If environmental protection and safety are emphasized, and high requirements are placed on odor and toxicity, water-based release agents are more suitable; For high-temperature molding processes or solvent-free demand scenarios, solvent-free release agents are more suitable. Mastering the correct usage method of silicone release agent can effectively improve production efficiency and ensure the molding quality of silicone products.

The use of kitchenware is a skill, and the same goes for silicone kitchenware. The maintenance and cleaning processes are both important to prolong the lifespan of the objects and increase their cost-effectiveness. Do you know how to maintain silicone kitchenware? Let me share with you the knowledge of maintaining silicone kitchenware.Firstly, when we buy silicone kitchenware, we first remove the labels on the kitchenware, and then clean it with detergent. While cleaning, we also need to prepare a pot of hot water for later use. Then, we put the cleaned kitchenware into the hot water and boil it for a few minutes, mainly for the purpose of disinfecting and killing bacteria.So when we use it, such as stir frying or frying, there is a lot of oil on the spatula. At this time, we cannot use steel balls or pot brushes to clean it, to avoid damage or scratches to the kitchen utensils. Use a regular dishwashing cloth and detergent to clean it. Place the cleaned kitchen utensils in a ventilated place or disinfect the cupboard for easy use in the future.In daily life, cleaning and regular maintenance of silicone kitchenware is really important, as it can prolong its use time and also consider one's own health.

Staining is a common problem with silicone products, and we often encounter situations where the surface of silicone products is very dusty. So, how should we deal with this situation? The phenomenon of sticking to dust and debris is due to the inherent chemical properties of silica, and the phenomenon of adsorption force is an inevitable factor in raw materials. Therefore, for silicone products used in daily life and placed in textiles, plush, etc., adhesion will definitely occur. However, for such phenomena, they need to be processed and solved by silicone product manufacturers.It should be noted that adsorption force is the main reason for the accumulation of dust powder in silicone products. Therefore, the additives in organic silicon and inorganic silicon are different in the raw materials. Different adsorption methods can reduce the silicon chain structure units in silicone materials. Adding a large amount of water during raw material mixing can destroy the adsorption strength of silicon hydroxyl groups and reduce the active proportion in silicone adsorption.After molding, silicone products belong to the untreated process, so the surface will have the ability to automatically adsorb dust. However, static electricity can be covered by electrostatic oil surface spraying to prevent adsorption ability. There are two methods of treatment. Before processing and production by silicone product manufacturers, anti-static glue is used to control the adsorption energy and anodization of silicone in the raw materials. Another method is to spray oil on the generated silicone product surface to achieve a smooth and anti-static effect.
