General Purpose Silicone Rubber for Extrusion
DESCRIPTION
General Purpose Silicone Rubber for Extrusion is a type of silicone elastomer that is specifically formulated to be processed through extrusion methods. This rubber is designed to have a balanced combination of physical properties, such as flexibility, durability, and heat resistance, making it suitable for a wide range of applications.
The material typically comes in a high-consistency form and requires a curing process, often through the use of a platinum or peroxide-based curing system, to achieve its final properties. Once cured, it exhibits excellent environmental resistance, maintaining its integrity against varying temperatures, UV light, and moisture.
