Silicone Sponge 20lb

Our closed cell Silicone Sponge has a density of 20lbs/ft³. It is a high performance gasketing and sealing material designed for a wide range of industrial and commercial applications. Silicone sponge can be used for applications requiring compression set resistance and an extensive operating temperature range of -76 to +446°F (-60 to 230°C). With its smooth surface finish and tight closed cell structure, silicone sponge offers sealing and insulation for preventing liquid and gas leaks.

Silicone sponge demonstrates excellent resistance to ozone, oxidation, ultraviolet light, corona discharge, cosmic radiation, ionizing radiation, and weathering which makes this material suitable for indoor and outdoor applications.
