Silico® Silicone Rubbers – Professional Silicone Rubber Manufacturer in China
High Temperature Vulcanized (HTV) silicone cures with heat, providing strong mechanical strength, chemical resistance, and durability at temperatures above 250°C.
Room Temperature Vulcanized (RTV) silicone cures at ambient conditions. RTV-1 is one-part, moisture-cured; RTV-2 is two-part, mixed for precise curing. Both offer fast cure and strong adhesion.
Liquid Silicone Rubber (LSR) is a platinum-catalyzed, two-part system for injection molding. It ensures high precision, rapid cure, and biocompatibility for medical and food-grade uses.
