Chemical Resistance Table

This chart rates the 2 basic product families we offer in a variety of fluids to show chemical resistance. For more specific information on other conditions that can impact chemical resistance see our page on environmental conditions.

Chemical compatibility is a key factor when specifying polyurethane seals for fluid-exposed equipment.

Samples of both polyether and polyester were immersed for seven days at 75 degrees Fahrenheit. The rating was based on the volume change according to the following key:

(1) = Excellent (2) = Good (3) = Fair (4) = Poor
