Chemical Resistance Guide c hemical r

1 Chemical Resistance Resistance guideThe data in the following tables was obtained from numerous sources in the industry. The information is based primarily on the immersion of unstressed strips in the chemicals at ambient temperature and, to a lesser degree, on field experience. The end user should be aware of the fact that actual service conditions will affect the Chemical Resistance . It should be noted in the following charts that the A rating does not mean or imply that material will perform within original specification.

2 The Chemical Resistance table should be used for reference only. It is the ultimate responsibility of the end user to determine the compatibility of the Chemical being used in his or her particular application. Contact Hayward for information on Eastar = Excellent, no effect B = Good, minor effect C = Fair, data not conclusive, testing recommended X = Not recommended. Ratings are based on testing at an ambient temperature of 70 F. The Chemical Resistance table is for reference only. End users should test to determine application valves, Solenoid valves, Diaphragm valves and all other valves with elastomers fully exposed to process media should derate elastomer scores by one level ( B becomes C , C becomes x ).
