 The concept of food silicone is very vague, and now there is no old professional standards to limit what is the food silicone. According to the popular explanation on the current network, food silicone includes two: some of which is the primary component of SiO2 · nH2O inorganic silica gel, and the other is the composition of silicone rubber. In our current understanding, food silicone is silicone and silicone rubber and the use of food related to the silicone. Food silica needs to meet a variety of food safety standards.

 The main component of SiO2 · nH2O inorganic silica gel is derived from silicic acid polycrystalline colloidal material. SiO2 · nH2O content of 98% or more, non-toxic and tasteless, chemical stability, in the normal under the caustic and hydrofluoric acid, not any acid and alkali salt reaction. Because it is a colloidal structure, it has many micropores and a large specific surface area. The silica pore size is about 8-10nm, the specific surface area of 300-500m2 / g, and the surface of hydrophilic, water has a strong absorption capacity, in the case of high humidity water up to 80% -100% of their own components The So the silicone can be used as food, medicine, external use of a single regulator.

 After refining the silicone and food products can be mixed with the amount of food directly to ensure that the food monotonous and food with food, and the human body without any side effects. There is also a food class of silicone called food purification silica gel, the use of inorganic silica gel surface adsorption force to get rid of impurities in the liquid. Food silicone rubber is made of silicone rubber

Points to reach the food safety standards of silicone rubber.

 The silicone rubber is a composition of rubber, is dimethyl silicone and other silicone monomer polymerization of linear polymer elastomer, referred to as SIR. The macromolecular backbone is a Si-O unit, and the monovalent organic group is a pendant group, and the general structural formula is shown in the figure, wherein R, R 'and R' 'are organic groups such as methyl, vinyl, , Trifluoropropyl, etc., the actual operation of the R, R ', R "choice to consider the group of biological lazy, to ensure that meet the necessary parameters, harmless to the human body. M, n is the degree of polymerization, is a wide range of changes in the integer.

 Food silicone rubber function excellent use of convenience mainly for food complex model, the production of a variety of food-related appliances, the production of medical equipment and food-related transport packaging.
