Closed Cell Silicone Sponge: Firm Density

Closed Cell Silicone Sponge is available in Soft, Medium and Firm densities. It is a high performance gasketing material designed for applications that require an excellent compression set resistance and a wide operating temperature range. The tight and uniform cell structure prevents water absorption per ASTM D1056 of less than 3%. The smooth surface finish improves the sealing capabilities by providing 100% surface to surface contact and promotes better PSA adhesion. Closed Cell Silicone Sponge is formulated per AMS3195, AMS3196, ASTM D1056, MIL-R-6130 Type II, ASTM D6576 Type II, MIL-R-46089, UL94 HB, UL94 V-0 and FDA.
