Description


Table of Selected polymers belonging to this polymer class (links are for CAMEO pages)

Polymer name Properties of Concern
Rubber, Natural
Polybutadiene (Buna) Compounded with a wide variety of materials
Polystyrene Compounded with a wide variety of materials
Nitrile rubber (NBR) Some NBR are blended with PVC and contain chloride
Styrene-butadiene rubber (SBR) Tendency to crawl; Compounded with a wide variety of materials
Acrylonitrile butadiene styrene (ABS) Compounded with a wide variety of materials
Ethylene Propylene Rubber (EPR)
Ethylene Propylene Diene (EPDM) - wikipedia link May be crosslinked with other products with sulfur vulcanization
Butyl rubber (Isoprene)
Neoprene (Polychloroprene) 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) Problematic class of materials
Silicone Rubber - wikipedia 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.
