Vinyltrimethoxysilane Description

Vinyltrimethoxysilane (2768-02-7) is a colorless transparent liquid with an ester odor, soluble in most organic solvents, insoluble in water. The pH is 7, but it is soluble in water at a pH of 3.0 to 3.5.

Vinyltrimethoxysilane is suitable for all complex shapes, all densities of polyethylene and copolymers, for larger processing process tolerance, filled composites, etc.
CAS 2768-02-7 silane has a high service temperature, excellent resistance to pressure cracking, memory, abrasion and impact resistance. Both coupling agent and crosslinking agent, applicable polymer types such as polyethylene, polypropylene, unsaturated polyester, etc., can also be used to improve the affinity between glass fibers, inorganic fillers and resins reactive to vinyl.

Vinyltrimethoxysilane: Guide

Vinyltrimethoxysilane is soluble in ethanol, isopropanol, benzene, toluene and gasoline, insoluble in water; hydrolyzed and soluble in water by mixing with aqueous solution of acid. Slowly hydrolyzed by water vapor in air to produce the corresponding silanol.

Application:
1. Vinyltrimethoxysilane is an important crosslinking agent for crosslinked polyethylene, with excellent electrical properties, good heat resistance and stress cracking resistance, so it is widely used in the manufacture of wires, insulation and sheath materials.
2. The cross-linked polyethylene made by this product as cross-linking agent has the advantages of good resistance to aromatic hydrocarbons, oil, stress cracking, high mechanical strength and good heat resistance.
3. It can improve and enhance the electrical and thermal conductivity, and improve the storage period of room temperature silicone rubber.
