SILICONE RUBBER

Silicone rubber is best known handling extreme environments and temperatures. It can normally handle temperatures at -150°F to 480°F. Silicone is water repellent and comes equipped with good UV and ozone resistance, fungus resistance, low compression set, tensile strength, elongation, and insulation from electricity, making it one of the most popular and versatile rubbers for many industries.

All silicone grades at Gasket Supply are available as thin as .008″ thick to 1″ thick and are offered in continuous rolls or cut to meet your precise requirements. All silicone grades come in a measure of hardness (durometer) as soft as 25 durometer, and as hard as 80 durometer. Standard colors include orange/red, black, gray, and white; special colors are available upon request.
