The raw materials for preparing silicone oil, silicone rubber, silicone resin and silane coupling agents are various silicone monomers. Thousands of silicone products can be produced from several basic monomers. The main organic silicon monomers include: methyl chlorosilane (referred to as methyl monomer), phenyl chlorosilane (referred to as phenyl monomer), methyl vinyl chlorosilane, ethyl trichlorosilane, propyl trichlorosilane, Vinyltrichlorosilane, v-chloropropyltrichlorosilane and fluorosilicone monomer, etc. Among them, methylchlorosilane is the most important, accounting for more than 90% of the total monomer, followed by phenylchlorosilane.

The key to the development of any polymer material lies in the development of monomer technology. The silicone industry is characterized by centralized monomer production and decentralized product processing. Therefore, monomer production plays an important role in the silicone industry, and the production level of monomers directly reflects the development level of the silicone industry.
