Polypropylene Chemical Resistance Introduction Among many of the positive attributes of polypropylene, it is probably best known for its resistance to highly aggressive chemicals. While polypropylene is highly resistant to many chemicals at room temperatures, its chemical resistance decreases with increased temperatures. This technical note provides a basic resistance rating for many chemicals. This table is meant to serve as a general guide and should not be used to guarantee performance since specific site and application conditions may cause specific concerns which cannot be addressed in a general table. This chart rates the chemical resistance of polypropylene resin according to the following code: Ratings: A = Excellent B = Good, Minor Effect, slight corrosion or discoloration C = Fair, Moderate Effect, not recommended for continuous use. Softening, loss of strength, or swelling may occur. D = Severe Effect, not recommend for ANY use.
