White Silicone Rubber, 68-78 °IRHD. Silicone rubber having both methyl and vinyl substituent groups on the polymer chain. Formulated using only those ingredients determined by the United States Federal Food and Drug Administration (FDA). Water and n-Hexane extraction tested in accordance with Code of Federal Regulations Title 21 (CFR21), Section 177.2600. Also complies with the requirements of USP 29, NF 24 2006: <87> Biological Reactivity Test ‘in vitro' and USP 26, NF 21, 2003: <88> Biological Reactivity Tests ‘in vivo' Class VI. ASTM & ISO designation = VMQ. Excellent heat resistance and low temperature flexibility. Used primarily for dry heat static seals. Low physical strength and poor abrasion resistance prevents dynamic sealing. |
