Triethoxyvinylsilane Description

Vinyltriethoxysilane (CAS 78-08-0) also known as Triethoxylvinylsilane, is a colorless to pale yellow liquid that is soluble in a variety of organic solvents.

Vinyltriethoxysilane is suitable for polymer types such as polyethylene, polypropylene and unsaturated polyesters, and can also be used to improve the affinity between glass fibers, inorganic fillers and resins reacting with vinyl. Commonly used in silane cross-linked polyethylene cables and tubing.

Triethoxyvinylsilane: Guide

Vinyltriethoxysilane is suitable for a wide range of complex switches, all densities of polyethylene and copolymers, greater process tolerance, filled composites and more. It offers high service temperatures, excellent resistance to pressure cracking, memory, abrasion and impact resistance.

Vinyltriethoxysilane is both a coupling agent and a cross-linking agent for polymer types such as polyethylene, polypropylene, unsaturated polyester, etc. It can also be used to improve the affinity between glass fibers, inorganic fillers and vinyl reactive resins.
