Silicone Rubber Sponge / Foam Profiles

EXPANDED, CLOSED-CELL SILICONE SPONGE / FOAM PROFILES

General Characteristics

Predominantly closed cell structure with an integral surface skin, leading to very low water absorption. High compressibility and low compression set over a wide temperature range. Good acoustic and thermal insulation properties. Suitable for long term continuous use from -60 to 400^oF (-50 to 200^oC) and for intermittent use from -100 to 500^oF (-75 to 260^oC). High temperature grade suitable for intermittent use up to +570^oF (300^oC). Manufactured in ISO 9000 quality assured plants.

Typical Applications

Thermal insulation; high and low temperature acoustic insulation.

High and low temperature gaskets and seals.
