Description
Table of Selected polymers belonging to this polymer class (links are for CAMEO pages)
| Polymer name | Properties of Concern |
|---|---|
| Rubber, natural | Vulcanized rubber may emit sulfur fumes that will tarnish metals and stain organic materials |
| 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) | 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 | 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. |
