Silicone Monomer Introduction
Silicone monomers are essential raw materials for producing various silicone products, including silicone oil, silicone rubber, silicone resin, and silane coupling agents. These monomers are primarily derived from the reaction of silica powder with chloromethane, forming what is known as crude monomer.
The two main types of silicone monomers are methyl chlorosilane (methyl monomer) and phenyl chlorosilane (phenyl monomer). Methyl monomers dominate the market, accounting for over 90% of total silicone monomer production. Phenyl monomers are synthesized using methyltrimethylsilane, magnesium, and halogenated compounds.
Key methyl monomers include:
- Methyltrichlorosilane
- Dimethyldichlorosilane
- Chlorotrimethylsilane
- Methyl dichlorosilane
These monomers serve as the foundation for thousands of silicone-based applications across industries, making them crucial in modern material science.

Silicone Monomer: Guide
Silicone monomers are essential raw materials for silicone production, with dimethyldichlorosilane accounting for over 90% of total monomer output. Phenylchlorosilane follows in production volume, along with other key monomers such as trimethylchlorosilane, ethylchlorosilane, propylchlorosilane, and vinylchlorosilane, which are indispensable for manufacturing specific silicone products.
These monomers play a crucial role in the production of high-temperature-resistant, radiation-resistant, and specialty-grade silicone oils, silicone rubbers, and silicone resins. Additionally, they function as anti-crosslinking agents and structural control agents in silicone rubber formulations, enhancing flexibility, strength, and ductility.
