Ethylene Propylene Diene (EPDM) - wikipedia link
May be crosslinked with other products with sulfur vulcanization. Butyl rubber (Isoprene) See Cameo Page
Neoprene (polychloroprene) See Cameo Page Chlorinated, may off-gas acids Polysulfide
May contain PCB’s, can cause damage to metals when in contact with stainless and carbon steels. polyurethane Spandex is the most similar to natural rubber Problematic class of materials Silicone Rubber - wikipedia See Cameo Page Off-gassing depends on the initial curing system, platinum based cures have no offgassing; condensation cures can produce acid, neutral or basic chemicals during curing; peroxide cures can produce ketones or chlorinated aromatic chemicals as the material ages and breaks down.
