Silastic
Download
Description
The silastic is made of 2 or more thicknesses of texturized fiberglass cloth laminated together with a red high temperature fireproof silicone. It is offered in a smooth, red oxide or regular finish.
Applications
This material is often used in smelters for tapping operation joints and tolerates high temperatures. The silastic can be use in many applications: gasket for oven door base, supporting part for thermal treatment, general sealing gasket, tadpole, conveyor skirt, high temperature mat, protection curtain, expansion joint and more.
Available with kevlar for a better abrasion resistance and mechanical performance. Max. temperature 600°F.
