The main chain of organosilicon material contains "silicon oxygen silicon" structure, and the side chain contains a small amount of organic groups. Therefore, it has the double advantages of organic and inorganic materials. It is resistant to high and low temperature, irradiation and weather (no double bond, not easy to be decomposed by ultraviolet light and ozone), hydrophobic, flame-retardant, bio inert, oil resistant, solvent resistant and other properties, which can not be compared with other materials.

Silicone rubber foam material (also known as silica foam / silica foam) is a kind of porous, low-density and compressible polymer elastomer material prepared by foaming and vulcanizing at high temperature after mixing raw rubber, filler, vulcanizing agent, foaming agent, etc. Nowadays, silicone rubber foam is widely used because of its excellent properties of silicone rubber and foam material. It has high elasticity of rubber, and has the properties of sound absorption, shock absorption and so on. It is mainly used for cushioning pad, sealing pad, sound insulation material, insulating material, aviation thermal insulation material and other high performance materials.
