Trisvinylsilane
Trisvinylsilane (CAS: 1067-53-4), vinyltris(methoxyethoxy)silane commercially known as Silquest A-172, is a trifunctional vinylsilane featuring a polymerizable vinyl group and three hydrolyzable methoxyethoxy groups. This low-volatility liquid serves as a coupling agent and cross-linker in mineral-filled polymer systems, dramatically improving adhesion between inorganic fillers and organic matrices in rubber, plastics, and composites. The vinyl group participates in peroxide-cured rubber vulcanization and free-radical polymerization, while the hydrolyzable groups bond to silica, glass, and mineral surfaces. Key applications include silica-reinforced tires, wire and cable insulation, fiberglass composites, and moisture-crosslinkable polyethylene systems. Its hydrophilic methoxyethoxy groups provide easier handling and faster hydrolysis than simple methoxy silanes. With proven performance in demanding reinforcement applications, this silane is essential for high-performance composite manufacturing.
– Rubber Reinforcement: Used as a coupling agent in silica-filled tire compounds improving tensile strength, abrasion resistance, and rolling resistance.
– Wire and Cable: Serves as a cross-linking and adhesion promoter in peroxide-cured EPDM and polyethylene insulation systems.
– Composite Manufacturing: Applied in fiberglass and mineral-filled composites enhancing flexural strength and moisture resistance.
– Moisture-Curable Polymers: Enables silane cross-linking of polyethylene and copolymers for hot water pipes and cable jackets.
