Vinyl Silane Polymer Crosile-1090 Features & Applications

High-activity vinyl silane polymer; single-step coupling of fillers to polyolefins.

Rapidly hydrolyses in moist air, forming stable Si-O bonds with aluminium hydroxide, magnesium hydroxide, kaolin, etc., while terminal vinyl groups graft into peroxide-cured EPDM/EVA, giving strong interfacial adhesion.

Main uses

Halogen-free flame-retardant cable compounds; also suitable for pre-treating pigments or fillers.

Benefits

faster dispersion│lower water uptake│smooth processing│balanced strength & toughness│chemical & stress-crack resistance│improved abrasion│stable electrical performance after moisture exposure
