How to choose high-quality silicone products? Silicone products, with their advantages such as safety, non-toxicity, strong flexibility, and resistance to high and low temperatures, are widely used in various scenarios such as household life, maternal and child products, and industrial sealing. However, the quality of products on the market varies greatly, and low-cost, inferior products may have issues such as substandard materials, susceptibility to aging, and excessive harmful substances, which can affect the user experience and even health. Mastering scientific selection methods is essential to choose silicone products that meet your needs and are of reliable quality, allowing them to provide lasting and practical value.   Identify material standards and establish a solid safety baseline Material safety is the core of silicone product selection, with a focus on the material grade and authoritative certification. Food-contact silicone products (such as kitchenware and maternity and baby products) must meet food-grade standards. It is advisable to prioritize products labeled as "food-grade silicone" or "medical-grade silicone". These materials do not contain harmful substances such as bisphenol A and heavy metals, providing peace of mind when used. Authoritative certification is an important guarantee of quality. You can check whether the product has international certifications such as FDA (Food and Drug Administration) and LFGB (German Food Contact Material Standard), or relevant domestic GB 4806 series standard certification. Avoid purchasing products without any material labeling and at extremely low prices, as these products may use recycled silicone or add inferior additives, posing safety hazards for long-term use. Examine core performance to ensure practicality and durability The performance of silicone products directly determines their service life and effectiveness, and the following points require special attention. In terms of flexibility, high-quality silicone products feel soft and elastic, quickly rebound after stretching, and show no signs of whitening or cracking; inferior products feel stiff or overly sticky, and are prone to deformation and damage. High and low temperature resistance is a key indicator. High-quality food-grade silicone can withstand a temperature range of -40℃ to 230℃, making it suitable for refrigerator storage, microwave heating, and other scenarios, without experiencing issues such as cracking or odor due to temperature changes. In addition, attention should be paid to the product's aging resistance. High-quality silicone products are resistant to yellowing, hardening, and embrittlement over long-term use, while inferior products may show significant wear and tear after just a few months of use. Adapt to usage scenarios and precisely select types Different usage scenarios have varying requirements for silicone products, necessitating precise matching based on specific needs. In household kitchen settings, kitchen utensils such as spatulas and scrapers should be made of food-grade silicone with moderate hardness, high temperature resistance, and minimal deformation. Additionally, they should have a burr-free surface and be easy to clean. For sealing components (such as bottle cap seals and pipe gaskets), emphasis should be placed on sealing performance and corrosion resistance, ensuring a tight fit and resistance to aging. In the maternal and child products scenario (such as feeding bottles and pacifiers), medical-grade silicone is required, which should be odorless, soft, and have undergone rigorous safety testing to avoid irritating the delicate skin and respiratory tract of babies. In industrial scenarios, silicone seals, insulating parts, etc. need to be selected according to the specific usage environment, using specialized silicone products with corresponding oil resistance, acid and alkali resistance, and insulating properties. Master identification skills and avoid inferior traps When shopping, you can identify the quality of silicone products through simple methods. First, look at the appearance. High-quality products have uniform color, smooth surface, no bubbles, and no impurities; inferior products have dull color, rough surface, and are prone to dust accumulation. Second, smell the odor. High-quality silicone products have almost no odor, while inferior products may have a pungent chemical odor, which may come from harmful substances and is detrimental to health. Finally, test the texture by touching the product with your hand. High-quality silicone feels soft and delicate, with full elasticity, and leaves no obvious marks after pressing; inferior products feel stiff, sticky, or overly loose, with poor elasticity. At the same time, choose to purchase through formal channels and check whether the product packaging clearly indicates the brand, material, and certification information, to avoid purchasing "three-no products".   Choosing the right silicone products can bring many conveniences to life and work. By carefully checking every aspect, from material safety, core performance, scene compatibility, to identification techniques, you can avoid most inferior products. High-quality silicone products are not only practical and durable, but also ensure safe use, making every use more reassuring and comfortable, and becoming a reliable helper in daily scenarios.

The yellowing and discoloration of silicone products is a well-known phenomenon among many consumers. Do you think that yellowing of silicone products is a normal phenomenon?   Why do silicone rubber products exhibit yellowing? In fact, silicone yellowing is not its essence. Silicone rubber collagen material is composed of tens or millions of molecular crystals, and different components can be added to it to change its composition freely. Therefore, even if hundreds of thousands of molecular chains are not affected by chemical reactions, yellowing will still occur, but it is limited by external factors such as vulcanizing agents, raw materials, anti yellowing agents, etc! When it comes to vulcanizing agents, many silicone rubber product manufacturers use ordinary vulcanizing agents, which can be applied to many products. However, when used as high transparency or semi transparent products, there is often yellowing when white is cast. Therefore, many silicone rubber manufacturers choose anti yellowing vulcanizing agents and add anti yellowing agents to ensure that there is no discoloration in high transparency and semi transparent products. This can ensure that the secondary odor vulcanization during high-temperature vulcanization production does not change color, and the product will not change color after long-term use! In addition, there are certain factors in the raw materials. Generally, the raw materials for silicone products are mainly reinforced with white carbon black, and the dosage of white carbon black is used to lower the material cost and adjust the performance differently. Therefore, while improving other properties, the anti yellowing effect is affected and changed. Therefore, with the essential changes of the material, it is subject to more changes, which affects its own quality! On the other hand, the lack of prepayment during the use of silicone protective covers can lead to yellowing of ordinary precipitation method silicone rubber. Therefore, transparent silicone products may have some yellowing effects. It is recommended not to expose them to long-term sunlight, contact with liquids, and other factors!

Rubber and plastic materials have long been an indispensable material in our daily lives. They are present in most industries and equipment products, with plastics and rubber products currently occupying the majority. Among the many materials, synthetic rubber is particularly prominent, and it is the only one that truly fits the category of our daily necessities. In recent decades, silicone rubber materials have gradually replaced rubber, plastics, and other composite elastic resins in various industries. So, where does it stand out in synthetic rubber? As we all know, silica gel products have unique material characteristics. It does not react with any material and does not conflict with any material. It has reached a consensus with any material, so the material naturally has a tasteless and non-toxic effect. Among many electrical products, many silica gel accessories seal rings and other products can play a good role in cushioning and shock absorption. In different environments, it can also play a good role in electrical insulation, oxygen aging resistance, light aging resistance, and good anti-virus and anti-corrosion performance. It remains calm and composed in high and low temperature environments, with the ability to resist cold and high temperature environments. It still retains its material physical properties in various high and low temperature environments. Currently, silicone products have a temperature resistance range of -40 to 280 degrees Celsius, and are widely used in the field of daily necessities due to their environmentally friendly and safe nature. They have also demonstrated excellent performance and are widely used in silicone gifts, silicone daily necessities, and electronic peripheral protective parts! Silicone rubber is also widely used in industries such as machinery, construction, textile, chemical, light industry, printing, etc. as insulation, packaging, sealing, moisture-proof, and earthquake resistant materials. As a soft film material, it is widely used in the manufacturing of cultural relics, handicrafts, toys, mechanical parts, etc. Semiconductors sealed with silicone rubber can be used for high-frequency communication in industrial motors, locomotives, power supplies that require high-voltage switches, mobile phone base stations, satellites, and radars. Toys made of silicone rubber are not afraid of tearing, have excellent tactile sensation, are easy to color, and can be disinfected at high temperatures. The game equipment made is durable and not afraid of wind and rain.

Silicone pads are used in every industry as one of the main accessories for cushioning, shock absorption, and gear protection. Their application has occupied a certain market distribution demand and can be seen everywhere in our daily lives. They are not as good as foot mats, anti slip pads, protective silicone pads, and cushioning and shock absorption pads. Many silicone adhesive pads are fixed by sticking double-sided tape to prevent detachment and sliding after too long. Therefore, under normal use, except for human conditions, 3M adhesive pads are unlikely to easily fall off because certain skills are also required in the backing process and processing. These experience skills can greatly improve the tightness of silicone adhesive pads. What are the specific methods for sticking gaskets? The prerequisite for making high-quality gaskets is definitely to do corresponding preparation work. For example, the main products of silicone gaskets are designed to achieve adhesive backing effect, which naturally cannot achieve good results. Therefore, it is required that the face of the silicone gasket be clean, dry, free of impurities, oil stains and liquids, and the surface of the gasket should be clean and smooth, without potholes, etc. There are usually two forms of silicone gasket backing, manual and fixture. Manual backing is mainly used for sampling and small batch trial production processing. It can be manually cut without a fixture die, and is not recommended for those with high requirements for edges and corners. Fixture dies are used for large-scale production processing. The premise of this method is that the silicone gasket processing manufacturer needs to prepare the mold opening method in advance, and the main method is self disassembly. After applying the backing adhesive, the edge can be removed by using a die. This processing technology has high precision and fast efficiency. Pressure is a secondary issue, and the usual debonding phenomenon is likely due to the magnitude of pressure. To achieve a good backing effect, pressure needs to be applied to the 3M adhesive and bonding surface to ensure sufficient contact and bonding between the adhesive paper and the gasket. Manual pressure is usually not as good as a scraper, and a scraper is not as good as a pulley. Different pressure instruments are used for different liquid machines and silicone gaskets with different requirements. The process of backing silicone gaskets is not complicated, and there are usually several reasons that can cause problems with the backing. In addition to the raw materials of the silicone gasket manufacturer and the 3M adhesive paper material, they are basically within the controllable range. Therefore, choosing a high-quality gasket supplier and materials is certainly important!

Some consumers have found that the edges of silicone products are damaged and cracked after purchasing them, which often troubles many friends and leads to a certain level of awareness and demand for silicone products in the future, resulting in a lower purchase rate. However, addressing the issue of edge damage in silicone products is not a last resort. The edge damage of silicone products is called "bursting edge" in the silicone products industry, which is mainly caused by several phenomena. During the use of the product, the misalignment phenomenon is caused by severe stress and the influence of the mold, resulting in slight damage to the silicone product and gradually increasing wear in the future. Secondly, the product itself has its own damage phenomenon. During the production and processing of silicone manufacturers, product damage is caused by temperature and material fixing problems. In addition, the hardness, softness, and curvature of the product also have a certain impact. Therefore, the causes of product damage can be controlled in various aspects! 1.Hardness issues are common in low hardness silicone products, and the main phenomenon of low hardness lies in the parameter adjustment of silicone product manufacturers, such as the temperature and secondary exhaust of the machine. Therefore, it is important to set the parameters of the machine, reduce the temperature, shorten the vulcanization time, and control the molding processing time of the product just at the stage of curing completion. If the time is too long, the raw material in the machine will expand, causing separation at the parting position and leading to cracking. 2.Raw materials are the key to silicone products. If the raw materials are not mixed for a certain period of time during the production process or if the added additives are insufficient, it may lead to various problems in the production process, such as edge bursting, poor fluidity, product bulging and deformation, etc. 3.The structure is relatively complex, and the phenomenon of edge breakage in products is also relatively large. In addition to hardness, the phenomenon of edge breakage in silicone products is usually closely related to the structure of the product in cases of low hardness. For example, the product is relatively thick, has a certain curvature, and the parting position is at the high point of the product. Therefore, strict control of its parting position is required during product design. 4.The mold is the key to the edge damage of silicone rubber products. During the development of the mold, the problem of product damage has not been solved due to inconsistent and misaligned connections between the upper and lower parting points. Therefore, strict control is needed in mold processing. 5.Other exceptional factors can also cause product edge breakage, such as improper control of the weight of the rubber material (too heavy can lead to edge breakage, while too light can lead to material and corner shortages, so controlling the weight within a reasonable range can reduce the probability of edge breakage). Secondly, in the long-term production process without intervals, the mold temperature should be appropriately reduced to maintain a certain temperature range (spraying the mold with clean water to maintain the mold temperature without intervals)

The silicone wristband is not only comfortable to wear on the hand, but the pattern on the wrist strap is also very attractive. So how are these exquisite patterns or logos made and engraved? What processes do silicone product manufacturers need to use in the production of wrist straps?   1. Printing Silicone printing, in simple terms, refers to the printing process using screen printing. The basic principle is that the mesh holes in the graphic and textual parts of the screen printing plate can pass through silicone, while the mesh holes in the non graphic and textual parts cannot pass through silicone. Apply a certain pressure to the silicone using a scraper to squeeze it from the mesh holes in the graphic and text parts onto the substrate. 2. Glue filling First, shape the product and then apply glue onto it. The main components of glue are adhesive colloids and organic solutions. The function of adhesive gel is to act as a bonding agent. The sponge mainly relies on the volatilization of organic solutions to achieve expansion during gluing. So when pouring glue, try not to expose the sponge that has been coated with glue to the outside, as this will reduce the expansion effect of the organic solution on the sponge. 3. Fuel injection Applied to spray on the surface of silicone wristbands to improve gloss and enhance hand feel and font lifespan. The product after extinction treatment has the characteristics of smooth hand feel, matte surface, and friction resistance, which can protect the printed fonts on the wristband and and prevent dust on the surface. 4. Radium carving Laser engraving, also known as laser engraving or laser marking, is a process of surface treatment using optical principles. Laser engraving refers to laser engraving, which uses the light energy of a laser beam to cause chemical and physical changes in the surface material of silicone products on the wrist strap, leaving marks, or to burn off some of the material with light energy, revealing the desired etched graphics and text. According to different carving methods, it can be divided into dot matrix carving and vector cutting.

Silicone hose is also very common in daily life. It is made of silicone raw material and is a highly active adsorbent material with an open porous structure, strong adsorption ability, and the ability to adsorb various substances. At the same time, it also has stable chemical properties, is non-toxic and odorless, and is a very safe and environmentally friendly material. What causes the aging of silicone products? Due to the aging of silicone products, many mechanical components cannot operate normally under specific conditions. Below are a few analysis reasons for your reference.   1. The effect of heat Raising the temperature can cause thermal cracking or cross-linking of silicone products. But the basic function of heat is still activation. Improving the oxygen diffusion rate and activating the oxidation reaction, thereby accelerating the oxidation reaction rate of silica gel, is a common aging phenomenon called thermal oxygen aging. 2. The role of oxygen Oxygen undergoes a free radical chain reaction with silica gel molecules in silicone gel, causing molecular chains to break or over crosslink, resulting in changes in the properties of silicone rubber products. 3. Reasons for light The shorter the light wave, the greater the energy. The destructive effect on silicone is caused by high-energy ultraviolet radiation. Ultraviolet radiation can not only directly cause the breakage and cross-linking of silicone molecular chains, but also generate free radicals in rubber due to the absorption of light energy, triggering and accelerating the oxidation chain reaction process. 4. The role of ozone Ozone has much higher chemical reactive oxygen species and greater destructive power. It also causes molecular chain breakage, but the effect of ozone on silicone gel varies depending on whether the rubber is deformed or not. 5. The role of water The role of water has two aspects: silicone products are prone to damage when exposed to humid air, rain, or water immersion. This is because water-soluble substances and components such as water droplets in silicone are extracted and dissolved by water. 6. The effect of mechanical stress Under repeated mechanical stress, rubber molecular chains will break and generate free radicals, triggering an oxidative chain reaction and forming a mechanochemical process. 7. Other reasons include chemical media, valence metal ions, high-energy radiation, electricity, and biology.   Due to the stable chemical properties of silicone hoses, they are resistant to both high and low temperatures. Even when heated, they do not produce toxic substances or deform. The silicone hoses widely used in medicine are food grade silicone hoses that are non-toxic and odorless. The pacifiers commonly used by children are also made of silicone, which is a food grade silicone material and has characteristics such as drop resistance and easy cleaning.

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. It is worth noting that the anti slip performance of both silicone and rubber 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.

In modern industry and daily life, silicone gaskets are widely used in many fields such as electronic appliances, food and medical care, machinery manufacturing, etc. due to their excellent performance, such as high temperature resistance, low temperature resistance, aging resistance, and good insulation. So, how are these seemingly ordinary silicone gaskets produced? The production of silicone gaskets begins with the careful selection of raw materials. High quality silicone rubber material is the key. It needs to have high temperature resistance, corrosion resistance, aging resistance and other characteristics to adapt to different application environments. If used in the field of food contact, it must also be food grade silicone material to ensure safety and reliability. Mold design and processing can be regarded as the core process of silicone gasket production. A mold is like a "template" for a product, and its design rationality directly determines whether the size accuracy and shape of the silicone gasket meet the standards. Dibo Silicone has a professional mold design team that uses advanced CAD/CAM technology for design. At the same time, during the mold manufacturing process, precision and surface quality are strictly controlled, effectively reducing production errors and scrap rates. And they will arrange the mold placement reasonably according to production needs to improve production efficiency. After the mold is opened, a trial mold will be conducted to carefully measure the product and verify it with the drawings to ensure the accuracy and reliability of the mold. Production molding vulcanization is a key step in giving silicone gaskets their final form. Common molding processes include compression molding, extrusion bonding, and liquid forming, each with its own applicable scenarios. Compression molding is the most common process, suitable for conventional sealing rings. By manually placing raw materials into molds, hot pressing and heating the materials to shape them, silicone gaskets of any structure such as rectangular, circular, and irregular can be produced; Liquid forming is suitable for complex and precision gaskets. The rubber material is pressed into the hot mold cavity through the injection nozzle of the injection machine for molding. The product material has good texture and good self disassembly, but the mold and material costs are relatively high; Extrusion molding is suitable for the production of large silicone gaskets. The extruded long sealing strip is cut into the required length and bonded into a circle. Although there may be gaps at the joint that affect the sealing effect, the advantage is that the size is not limited. Quality inspection runs through the entire production process. From strict inspection of raw materials upon arrival at the factory, to inspection during the production process, and to comprehensive testing of finished products, every step must not be neglected. Visually inspect whether the surface of the silicone gasket is flat and smooth, and whether there are defects such as bubbles and cracks; Use professional instruments to measure thickness, length, width, etc. for size inspection to ensure consistency with design requirements; Performance testing evaluates the key performance of silicone gaskets, such as high temperature resistance, aging resistance, and sealing. After production and testing are completed, the silicone gasket will enter the packaging process. From raw material preparation to final product, the production of silicone gaskets embodies the crystallization of numerous processes and technologies. Every production process is crucial, as they together ensure the excellent quality of silicone gaskets, enabling them to play an important role in different fields and provide reliable support for people's lives and industrial production.

Why do bubbles appear on the surface of silicone products, and what should be done if bubbles appear? What is the reason for this? Below, silicone product manufacturers will explain the solutions to the occurrence of bubbles in silicone products:   The most important thing is to consider the issue of silicone vulcanization process. After carefully studying and practicing the three elements of silicone vulcanization, what we should consider is: 1. Measuring the real mold temperature. How many parts of rubber vulcanizing agent have been added. 3. Check if the vulcanizing agent has failed, and cover the rubber material with a thin film. The specific operation method is as follows: 1.Control the temperature of silicone molds: Generally, the temperature of the upper mold is high and the temperature of the lower mold is low, because the lower mold needs to discharge materials, and if the temperature is too high, it is easy to burn. 2.It is well known that sulfurizing agents are prone to volatilization, so it is important to take precautions. 3.The dosage of vulcanizing agent added should be appropriate. 4.The vulcanization time can be appropriately extended 5.You can consider spraying some detergent solution. The above solutions for the appearance of bubbles on the surface of silicone products are for reference only. For more information on silicone process issues, please continue to follow us.
