1. The silicon resin
Silicone is a highly cross-linked thermosetting polysiloxane polymer, which has the dual characteristics of organic resin and inorganic material, unique physical and chemical properties, good electrical insulation, temperature resistance and waterproof effect.
Silicone is a thermosetting resin. It is usually a mixture of methyl trichlorosilane, dimethyl dichlorosilane, phenyl trichlorojian, diphenyl dichlorojian, etc. Hydrolyzed in the presence of toluene into linear, circular and cross-linked polymers.
After acid removal, further polycondensation is performed to form a highly cross-linked silicone resin with a 3D network structure.
Silicone can be added to fillers, such as silica, quartz powder, mica powder, glass fiber and catalysts, and processed by mixing and rolling into silicone mold plastics. The outstanding property of silicone is its excellent thermal oxidation stability. It also has excellent water resistance, moisture resistance, corrosion resistance, ozone resistance and weather resistance, and is used as a waterproof coating in buildings.

2. The silicone rubber
Silicone rubber is a rubber whose backbone consists of alternating silicon and oxygen atoms, and the silicon atoms are usually connected to two organic groups. Ordinary silicone rubber consists mainly of a silicon chain containing methyl groups and a small amount of vinyl. The introduction of phenyl group can improve the high and low temperature resistance of silicone rubber, and the introduction of trifluoropropyl and cyano group can improve the temperature resistance and oil resistance of silicone rubber. Silicone rubber is one of the most important products of silicone polymer. It is widely used because of its excellent resistance to high and low temperature. Silicone rubber is mainly divided into high temperature mixed silicone rubber and room temperature vulcanized silicone rubber.

3. Silicon monomer
Silica gel products are many, there are tens of thousands of grades and brands, there are more than 5000 kinds of commonly used. But its raw materials are concentrated in several monomers, especially dimethyl dichloride, which accounts for more than 90% of all monomers. And then there's phenyl chlorine.
Silane, trimethylfluorosilane, ethyl and propyl chlorosilane, vinyl chlorosilane, etc. The monomer production process of silicone resin is complicated and the process is long.

4. Silicone oil Silicone oil is a chain of different degrees of polymerization of polysiloxane. Usually organic groups are methyl groups, called methylsilicone oil. Common organic groups are C group, phenyl group, hydrogen group and so on. General silicone oil colorless or slightly yellow, tasteless, non-toxic, not volatile.
 non-corrosive oil. The viscosity increases with the increase of molecular weight, so there are silicone oil products with different viscosity.
