Name: Methyltrichlorosilane (M1)

Feature: This product is a colorless transparent liquid. It is the main material of silicone products to produce methyltriethoxysilane and silane crosslinking agent (methyl triethoxysilane and methyltrimethoxysilane), and produce silicon resin, special coatings, building waterproofing agent, and oilfield drilling collapse resistance agent for methyl sodium silicate used in drilling wells on the oil field.

CAS No.: 75-79-6

Application of Methyltrichlorosilane

It is mainly used for the production of methyl triethoxysilane, methyl trimethoxysilane, and other crosslinking agents, silicone resin, special coatings, construction waterproofing agent, and oilfield drilling anti-collapse agent (sodium methyl silicate), as well as gas-phase silica and other products.

Silicone materials, including methyl trichlorosilane, are not only as special materials used in military, aviation, aerospace, and other cutting-edge industries, but also widely used in construction, textile, automobile, machinery, electronic and electrical appliances, chemical and light industry, leather and papermaking, medicine and health, etc. To a certain extent, it reflects the development of a country.

Production Methods of MethylChlorosilane

There are two production methods of methyl chlorosilane-indirect method and direct method. It was invented by E.G. Rojo in 1940 and is produced by using copper or copper salt as the catalyst to make a direct reaction between methyl chloride and silicon powder at about 300℃. This is a complex non-homogeneous reaction. The resulting mixture mainly contains dimethyldichlorosilane (about 70%), followed by methyl trichlorosilane, trimethylchlorosilane, methyl dichlorosilane, etc. The product can be obtained by distillation. The product is obtained in pure form by distillation. Due to the exothermic nature of the reaction, temperature control is extremely important, and most fluidized bed reactors are now used.

Storage and Transportation of Methyltrichlorosilane

Storage: Stored in a shady, cool, and ventilated place. It should be kept away from kindling and heat sources, avoid direct sunlight.

Transportation: When transported, avoid rain and direct sunshine.

Description of Silane Crosslinking

Silane crosslinking is introduced into polyethylene by a silane coupling agent to increase the strength and aging resistance of polyethylene.

Since its introduction in the late 1960s, silane-based cross-linked polyethylene technology has grown considerably and gained wide application.
