CLOSED CELL SILICONE SPONGE MEDIUM DENSITY
DESCRIPTION:
Silicone Sponge is an excellent material for gasketing applications that require a soft, compressible material. It is resistant to extreme temperatures and offers good compression set. The surface has a fine fabric finish and is available in continuous rolls up to ½” thick and sheets up to 2” thick.
KEY CHARACTERISTICS:
- Extreme High & Low-Temperature Resistant -85ºF to +450ºF (Intermittent)
- High Compressibility
- Low Compression Set
- Excellent gasketing material
- UV / Ozone Resistant
- Specifications: AMS3195, Mil-R-46089, ASTM D1056, Mil-R-6130, Mil-Std 670 TE12, Formulated to meet UL94HB
