Rubber Chemical Resistance Chart

Welcome to our Rubber Chemical Resistance Chart

Here is the rubber compatibility chart that rates all popular rubber materials that comes into contact with various chemicals. Use this rubber chemical resistance chart to make sure that the elastomer or O-ring seal you choose will be compatible with the particular environment. The chemical compatibility of rubber is extremely important as the rubber can degrade rapidly if the rubber material is not compatible with the environment or media that it comes into contact with.

LEGEND: 1 = Satisfactory, 2 = Fair, 3 = Doubtful, 4 = Unsatisfactory, X = Insufficient Data
