Momentive HTV Silicone Rubber Products

I. Product Overview

Momentive (formerly GE Toshiba Silicones) is a global leader in the silicone industry. Its HTV (High-Temperature Vulcanizing) silicone rubber is renowned worldwide for exceptional heat resistance, weatherability, electrical insulation, and mechanical performance. HTV silicone rubber is a high-consistency elastomer that requires heat vulcanization for molding. It is suitable for extrusion, calendering, and various molding processes including injection, compression, and transfer molding.
