At present, there are 90% silicone products on the market, solid silica gel production, especially silica gel kitchen products, such as silicone placemat for kid, silicone baking mat and so on, 100% are solid silica gel production. Silica gel products can be divided into three major types according to the forming process. Molded silica products: solid silica gel production is an oil pressure molding process, the core factor is time, temperature and pressure. Molded silicone products is usually the mold temperature in solid silicone raw materials adding curing agent after vulcanization machine pressure, high temperature sulfur into solid molding, molded silicone hardness usually at 30 DEG C-70 DEG C.

The extrusion of silicone products, usually through extrusion machine extrusion molding silicone, silicone extrusion general long tubular shape, can be easily cut, but the shape of silica gel extrusion have limitations in medical devices, widely used in food machinery; liquid silicone products, injection molding is through silica gel injection molding products, soft, hardness can reach 10 DEG C-40 DEG C, because of its soft characteristic, in the simulation of human organs, medical Guijiaoxiongdian, widely used.

Special silicone products, according to the chemical properties of silica gel or some auxiliary materials, special silicone products also has a high temperature (up to 330 degrees), food grade (complete with the United States FDA, LFGB standard), medical grade, flame retardant, by adding auxiliary raw materials can also have negative ion, luminous, color the characteristics, etc..

In twenty-first Century, environmental protection material, silica gel made of daily articles more and more demand, especially silicone placemat for kid, silicone gloves and other silica kitchen products. At an annual rate of more than 18% growth, the main market is Europe and the United States and Japan and other developed countries. 90% of these silica kitchen products are made of solid silica gel. The main process is oil forming. When solid silica gel is produced, time, temperature, pressure and material weight become very important factors. Solid silicone production of silicone placemat for kid is generally used 50# steel, a higher requirement for silicone products are generally P20 ace steel mold, such products more smooth appearance, and has a silicon mold with long service life.
