Low Compression Set, Red Silicone Rubber, 66-75 °IRHD. Silicone rubber having both methyl and vinyl substituent groups on the polymer chain. Compounded in accordance with FDA requirements.

Low compression set grade, offering excellent heat resistance and low temperature flexibility. Used primarily for dry heat static seals, low physical strength and poor abrasion resistance prevents dynamic sealing.
