The use of silica gel in the market because it will not release toxic substances and feel soft and comfortable, ability of high temperature and low temperature ( - 60c~+300c) Good physical and chemical is widely used, there are few he polymer can match it. Powerful elastomer, and more than a rubber sealing, excellent electrical insulation and resistance to chemicals, fuel, oil, water, coping with bad environment of good material. , etc. , and can distinguish between solid and liquid silicone products manufacturing process, the former thermal transfer, by which the raw material is given priority to with injection molding, the liquid on the investment in equipment and raw material cost is high, but its production speed, low degree of processing, and other factors, such as less waste to observe, using liquid silicone injection molding, injection production in the pursuit of precision, speed, automation industry, must be oriented trend in the future. The difference between the liquid silicone and solid silica gel! Raw material is you can see, a solid to a liquid. Now here to discuss the difference of two materials: 1, the shape of liquid silicone and solid: ( 1) As the name suggests liquid silicone is in liquid state, liquid ( 2) Solid silica gel is a solid, not liquid. 2, liquid silica gel and the use of solid silica gel: ( 1) Liquid silicone commonly used in baby products and kitchen supplies and medical supplies can be direct contact with food and the human body, 2) Solid silicon generally use the articles for daily use and miscellaneous pieces of industrial and automotive parts, etc. , apply more extensive, 3, solid silica gel and the safety of the liquid silicone: ( 1) Liquid silicone is high transparent high security of food grade material, molding without adding curing agent and other auxiliary materials, sealed feeding forming. ( 2) Solid silica gel is transparent environmental protection material, molding need to add curing agent accelerate vulcanization molding time, open mode of feeding forming, 4, liquid silicone and solid silica gel forming method: ( 1) Liquid silicone injection molding liquid silicone rubber ( LSR) : the full name for the injection molding liquid silicon rubber, curing equipment for injection moulding machine. Injection molding machine has a technological process is very simple, Don't need to be in the process of high temperature glue ingredients, mixing, blanking, material and process, only one of the workers take products) , the products are high precision, All artificial program before molding all replaced by a machine) With high yield ( A/B glue mixing, under A certain temperature for A few seconds to shape) , save, save electricity, save material and so on many advantages, can produce all glue products! Is a mainstream in the development of silicone rubber material in coming years. ( 2) Solid silica gel forming is raw material and a solid shape, and silicone manufacturers through mixing, mixing machine and cutting machine cut into product and mold the right size and thickness, a mold, after pressure molding machine under a certain temperature. Stripping along the lines of the plastic products, also need to clean up the mold and so on. 5, liquid silicone and solid state how the difference between high transparency liquid silicone, silicone products without peculiar smell, product has the injection gate. The transparency of solid silica gel, have cover the fragrance of vulcanizing agent, vulcanizing agent or other products without the injection gate.
