Rubber Chemical Compatibility
What Chemicals are Compatible with Natural Rubber, SBR, GRS, Butyl, EPR, EPT, EPDM, Buna-N, Nitrile, NBR, Neoprene, Hypalon, Polyurethane, Polysulfide, and Silicone? The chemical compatibility of elastomers is crucial since rubber can degrade rapidly if the material is not compatible with the chemicals it touches.
Rubber Chemical Compatibility Chart: Check the chemical compatibility of nitrile, buna and polyurethane rubber with various chemicals, solvents, alcohols and other products.
Please Note: The information in this rubber compatibility chart has been supplied by reputable sources and is to be used ONLY as a guide in selecting equipment for appropriate chemical compatibility. ALWAYS test your equipment under the specific conditions of your application before permanent installation.
Ratings of chemical behavior listed in this chart apply at a 48-hr exposure period. We have no knowledge of possible effects beyond this period. We do not warrant (neither express nor implied) that the information in this chart is accurate or complete or that any material is suitable for any purpose.
