Introduction to food silicone-HongYe silicone Date:2013-04-23

The concept of food silicone is very vague, and there are no mature industry standards to limit what is food silicone. In accordance with the popular explanation on the current network, food silicone includes two parts: one is the inorganic silicone whose main component is SiO2·nH2O, the other is a synthetic silicone rubber. Food silicone is a kind of silicone rubber related to the application of food with our current understanding, and it needs to meet a variety of food safety standards.


Inorganic silicone is a kind of inorganic polymer material formed by the silicate, whose main component is SiO2 · nH2O. The content of SiO2·nH2O in it is more than 98%. It has these features of non-toxic, odorless, stable chemical performance and no reaction with any salt except caustic alkali and hydrofluoric acid in the normal state. It is a colloidal structure, so it has a lot of pores and large specific surface area. The pore size of silicone rubber is about 8-10nm and the specific surface area is 300-500m2/g. Furthermore, it has a strong absorption of water, and the capacity of absorbing water is up to 80 %-100 % which is equivalent to its own weight in the case of high humidity. So, the silicone rubber can be used as external desiccant for food and medicines.

The food grade silicone rubber after refining can be mixed with food and medicine according to the requirements in order to guarantee the food is dry. It can be consumed together with food, but does not produce any toxic and side effect to human body. There is another kind of food silicone, called as food purification silicone rubber, which can eliminate the impurities in the liquid by the surface adsorption of inorganic silicone. Food Silicone rubber is a synthetic silicone rubber, which can meet the food safety standards.


Food silicone rubber is a linear polymer elastomer polymerized by dimethyl siloxane elastomer with other organic silicon monomer, hereinafter referred to as SIR. Macromolecular main chain is based on the Si - O unit, with monovalent organic groups as side group.


Food silicone rubber with excellent performance and easy to use is mainly used for making all kinds of instruments associated with food, the food complex mode, medical instruments and the packing related to food and so on.
