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.

Provenance — what every record carries

Every record carries source (the URL the value was read from) and source_quote (a verbatim quote from that page stating it). A value you cannot check against its page is indistinguishable from an invented one; these can all be checked. Each record is also individually addressable on the canonical site at its url.

Licence position

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).

Facts are not copyrightable; what this dataset takes from each source is a fact plus a short attributed quote linking back to the page that states it.
