Description

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

Polymer name	Properties of Concern
Polybutadiene (Buna)	Compounded with a wide variety of materials
Polystyrene	Compounded with a wide variety of materials
Nitrile rubber (NBR)
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 See Cameo page Compounded with a wide variety of materials. Ethylene Propylene Rubber (EPR) See Cameo Page 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.
