Summer is a season with the most high temperature days of the year, as the temperature continues to rise, the intensity of ozone and ultraviolet rays is getting higher and higher, resulting in the rapid aging of silicone products, resulting in the life of silicone products reduced, so how to prevent the aging of silicone products in summer?   1. Prevent silicone products from being ventilated and dry, and avoid direct exposure to sunlight; 2. Soak in water for a while, because silica gel has strong hygroscopic ability; 3, in the surface coating of silicone products or add light screen agent, add paraffin wax and other treatment to avoid premature aging of silicone products; 4. Add about 1% amine or phenolic additives in silicone products, which can effectively prevent the effect of heat, oxygen, light and liquid. For silicone products, raw materials of silicone products will have a storage period, and the temperature has a great relationship, if the temperature is about 20°C, silicone products can generally be stored for three years without problems. If stored at 35°C to 40°C, it is likely that silicone will stick together in less than a year, so try to use silicone products within the specified period. In summer, we need to check silicone products often, if there is cracking, adhesion and other phenomena need to be dealt with quickly, do a good job of maintenance measures can ensure unnecessary losses, can also ensure the use of silicone products time.

Conductive Silicone is a type of silicone material that is made from basic silicone rubber and carbon, usually in the form of carbon black or conductive granules. Its properties make it ideal for applications requiring strong electrical conductivity, like static charge reduction and EMI (Electro-magnetic Interference) shielding. The silicon base offers a degree of flexibility that allows it to be used in a variety of ways and also makes it resistant to heat, making it ideal for applications where it must remain stable in a wide range of temperatures without compromising its electrical properties. The carbon component of the silicone acts as the electrical conductor, allowing for the transfer of electrical current. The carbon used can be varied depending on the desired electrical properties of the material, including electrical resistance and conductivity. Conductive silicone is used in a number of applications, ranging from medical and aerospace to automotive and consumer electronics. It is often used in gaskets, seals, and other rubber components to improve the electrical properties of these products. It is also used as a shielding material to reduce interference from electromagnetic waves, as well as a static dissipative material to reduce static charge buildup. Overall, conductive silicone provides a unique combination of flexibility and electrical properties, making it an ideal choice for a variety of industrial, automotive and consumer electronic applications.

1.Start from the source, that is, silicone raw materials, add antistatic agent in raw materials, can effectively control the generation of static electricity, in the production, can be installed in the silicone raw material jet molding machine feed electrostatic elimination device, air humidifier in the workshop, also can prevent silicone products from generating static electricity!When static electricity is generated, static electricity can be eliminated on silicone products, such as electrostatic eliminator, ionic wind elimination rod and other tools, these equipment can produce a large number of positive and negative ions, to eliminate static electricity effect! At the same time, we can also carry out static prevention on silicone products, but also can prevent static electricity on the premise of not damaging silicone products! 2.Ionic wind bar and electrostatic eliminator can effectively eliminate the static electricity generated by silica gel sheet during high-speed drawing, prevent the sheet from absorbing dust in the air due to static electricity or sticking between sheets due to static electricity, and effectively improve the product grade and quality of plastic sheet after production and processing. The annular electrostatic elimination device installed in the silicone injection molding machine silicone feed port, can eliminate the high voltage static electricity generated in the feed flow process, prevent the electrostatic cause of the feed mass blocked and affect the production. Antistatic agents can also be used to spray antistatic paint on the surface of the product without damaging the product performance and transparency. Anti-static liquid can be added in the compound, so that the inside and outside of the daub two layers, liquid and alcohol similar! 3.Spray oil. Spraying oil on the surface of silicone products can not only eliminate electrostatic trouble, but also increase the smoothness and color of the surface of the product. However, this method has limitations. Maternal and child products and medical products should not be sprayed with oil because of the impact on the health of infants.  

Silicone rubber products are widely used for its excellent properties like high temperature resistance, electrical insulation and external flexibility, among which, the most obvious feature lies in its odorlessness. However, in recent years some silicone rubber products have been found to have odors. What causes the odor of these products? The main cause of the odor is bacteria generated from raw materials and never property purified. For example, styrene, a major component of silicone rubber, can easily generate bacteria when exposed to air or moisture-containing environment during storage and transportation. In addition, additives used in silicone rubber, such as stabilizers, softeners, accelerators and fillers, may also act as a source of odor if the amount or quality is not well controlled. Finally, improper production processes can also cause the silicone rubber to emit odors. Thus, it is necessary to maintain good hygiene during the production process, optimize the production process, and use high-quality raw materials to avoid the odor of silicone rubber products.

So what is the hardness of all kinds of silicone products? What is the difference in hardness of different silicone products? What is the hardness standard of silicone products? Hardness standard of silicone products: Generally, for the products with large elasticity or soft feel, testers can directly determine the use of Shore HA hardness tester, such as: stationery plastic water bottle, TPUTPR plastic film bag and other products. And feel basic little elasticity or hard can be used to test Shore HD hardness tester, such as: PCABSPP and other products. If the degree is Shore xxHA, the hardness is relatively low. If it is Shore xxHD, the hardness is relatively high.   What are the differences in hardness of various silicone products? According to the use of various fields to choose different hardness of silicone products, Mix low hardness can do about 10 degrees, special silicone products can reach about 280 degrees! The commonly used silicone products are between 30 degrees and 70 degrees. There is also ordinary silicone products, can not be done with liquid silicone technology, there will be problems such as: silicone products are not good self-disassembly, the material is different, which leads to a problem is that the raw edge of the product is not smooth, the appearance of burr. So liquid silicone is suitable for low degrees of silicone products. The other is the ordinary silica gel process, that is, the solid silica gel product process. At present, the whole silica gel industry internal solid silica gel product process can do the low softness is 30 degrees, the max height is 80 degrees, although higher degrees can also be done, but the defect rate is too high, the product is brittle, and it is not good to self-disassembly. So solid state technology is most suitable for soft and hard degrees between 30 degrees and 70 degrees. Can not do more soft products, but self-disassembly better, the product appearance is beautiful, no burr. The hardness of silica gel and ordinary rubber is the same, Shore hardness is used to distinguish, generally the higher the hardness is harder, the hardness of silica gel raw materials can reach 0 degrees -90 degrees. Silica gel raw materials are divided into solid silicone and liquid silicone, solid silicone (mixed silicone) hardness can reach 20 degrees -90 degrees, commonly used for 30 degrees -70 degrees. And if you want to demand lower hardness of silicone raw materials, it will need to use liquid silicone, liquid silicone hardness is 0 degrees -20 degrees, commonly used for 10-20 degrees. In general, we use the most contact with the most widely is solid silica gel (mixed silica gel), in processing molding is more commonly used in the hardness of 30 degrees -70 degrees, if there are special needs of solid silica gel hardness can reach 20 degrees, the hardest can reach 90 degrees, but the lower the hardness of the molding process is more difficult. And silicone hardness if reached 80 degrees -90 degrees, in the mixing process is more difficult, the use of machinery and equipment is not the same. And high hardness silicone raw materials in molding scrap rate is very high, the product is very brittle, not good self-disassembly. Therefore, if you want to produce silicone products, the most appropriate hardness should be between 30 degrees -70 degrees.   Different hardness of silicone products will bring what aspects of the impact: 1, the change of extrusion strength, low hardness products will gradually decrease in strength, high hardness will increase, 5-10 degrees of difference will have different extrusion changes. 2, the change of tear resistance, the higher the hardness of the product tear resistance will be weaker, especially with the right Angle of the product is easy to tear, the lower the hardness of tear, the better the hardness is different. 3. Constant elongation stress causes deformation. Constant elongation stress is an important control index of silicone material, which is precisely related to hardness. 4, the change of wear and fatigue, different hardness of products have different effects on wear and fatigue, generally silica gel material with the increase of crystallinity hardness increases, long-term run-in will affect the phenomenon of fatigue decline wear-resistant enough. 5, the difference of elasticity, elasticity is one of the important elements in the silicone material, so the material of different hardness has an impact on each different application of the product, and the hardness of the ± difference is too large may lead to the use of the whole product, and even affect each link of the whole!

Sublimation Printing – In this process, the dyes used are solid at room temperature but turn into gasses when transferred onto the item being printed on. The dyes are injected into the substrate, usually silicone, and then heated until they turn back into solid form, leaving a colorized design on the substrate. Screen Printing – This process requires the use of a screen stencil. The screen is made of mesh fabric, and a negative image of the desired product is printed onto the mesh fabric and cured. The mesh fabric is then stretched onto a frame and places into a screen printing machine. Ink is then manually pushed through the mesh openings, creating an imprint onto the substrate. Pad Printing – Also known as ‘tampon printing’, this method uses a silicon pad and stencil to transfer ink from the pad onto the substrate. The ink is transferred from the pad to the substrate by repeatedly pressing onto the desired area and then lifting off. This process can print onto curved surfaces as well. Laser Engraving – This is the process of using a high-powered laser beam to remove the silicone material from the substrate, leaving behind an imprint of the desired design. The laser heats up the silicone and melts it away, creating the intricate designs. Thermo-Printing – Thermo-printing is the process of transferring a colored ink onto the silicone substrate. A ribbon is heated up, melting the ink and covering the substrate with the desired design.

Silicone products and rubber products are two kinds of products in the same industry. They both possess advantages and just have a few small differences. The main difference between the two is that silicone is classified as a synthetic rubber and rubber is natural. Also, silicone retains its elasticity and flexibility for much longer, potentially for the lifetime of the product, and can withstand more extreme temperatures than rubber. Both materials are used for a variety of products from medical supplies to automotive parts, but silicone is most popular for use in industrial products where cleanliness, sanitation, and resistance to particular chemicals are important. Rubber has several advantages due to the fact that it is natural, with the first (and perhaps most important) being that it consists of certain organic compounds that can resist certain organic compounds and bacteria. Its low cost and light weight make it a popular product for applications like car parts and gaskets. Rubber also possesses good insulation and elasticity. Silicone products are more expensive and less durable than rubber, but their ability to withstand extreme temperatures within the range of –50 to + 200 Celsius degrees, their low toxicity, and lack of sensitive functional chemistry means they are ideal for products that require a safe and resilient material. Other advantages include greater flexibility, resistance to solvents, and inert nature, which makes them non-reactive with other chemicals. Both rubber and silicone products offer advantages that make them ideal for certain products or applications. The choice between the two will depend largely on the application and function of the product itself.

Silicone products in the molding process a little attention will appear some adverse phenomena. For example, silicone products have poor elasticity. And some of the more frequently used silicone parts have certain requirements for tensile toughness, and the product mainly needs his tensile toughness to maintain. Therefore, in some manufacturing industries, the silicone material used in the mechanical industry will be useless once there is insufficient pull strength, springback shock absorption failure, and other performance of the product will be useless. Therefore, the operation of personnel in the molding process, the modulation of the machine, the coordination of raw materials are the key to the toughness and poor product.

Check the mold to see if the mold wear is relatively large, the accuracy is not high enough, resulting in the production of silicone sleeve burr more, difficult to deal with the problem. Curing temperature is too high or curing time is too long. Once the temperature of silicone products is too high, it will lead to numbness or brittleness after forming, which has a great impact on the subsequent edging. Long curing time is also one of the main reasons for brittle products. Vulcanization temperature is too low or vulcanization time is too short, vulcanization temperature is too low, vulcanization time is too short will also have a certain impact on the edge, silicone rubber products have a strong flexibility when not completely vulcanized, so it is difficult to remove the rough edge and product separate. From the production to solve these fundamental problems, we believe that the problem of silicone rubber products with rough edges can be well solved.
