Material Notes:

Red iron oxide filled, Phenyl Silicone Rubber, 65-75 °IRHD. Silicone rubber having methyl, vinyl and phenyl substituent groups on the polymer chain. Meets UK Ministry of Defence aerospace specification DTD818 Class M4 (now obsolescent and inactive for new design). ASTM & ISO designation = PVMQ.Applications: Excellent heat resistance plus ultra-low temperature flexibility. Used primarily for dry heat static seals. Low physical strength and poor abrasion resistance prevents dynamic sealing. Although silicone will swell in petroleum lubricants, this is not necessarily detrimental in static sealing applications.
