The compatibility rating of a chemical against thirteen common elastomer families, as published in an industry chemical resistance chart. Each record is one chemical carrying its rating for Nitrile (NBR), EPDM, Neoprene (CR), SBR, Silicone (VMQ), Butyl (IIR), Polyacrylate (ACM), Hypalon (CSM), Viton (FKM), Polyurethane (AU/EU), Fluorosilicone (FVMQ), Aflas (TFE/P), and Kalrez (FFKM). Answers 'is Viton compatible with acetone', 'which elastomer resists sulfuric acid', 'can I use EPDM with gasoline', and 'Nitrile vs EPDM for sodium hydroxide'. Ratings use a 1-4 scale: 1 = Satisfactory, 2 = Fair, 3 = Doubtful, 4 = Unsatisfactory, X = Insufficient Data.

Chemical compatibility ratings are factual engineering data published by manufacturers and distributors as free technical resources. Each record quotes a short attributed span from a publicly available chart and links back. Facts are not copyrightable (Feist, 1991).
