Material Notes:
Low Compression Set, Blue Silicone Rubber, 65-75 °IRHD. Silicone rubber having both methyl and vinyl substituent groups on the polymer chain. ASTM & ISO designation = VMQ.Applications: 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.
