Stain Resistance

Plastic materials that resist staining

Stain resistance refers to the ability of a polymer to resist discoloration by a staining agent such as ketchup or berry juice. PEEK and PET have exceptional resistance to staining and are widely used in food processing equipment and pharmaceutical manufacturing machinery.

A plastic material’s resistance to staining will depend on a number of factors including the concentration of the staining agent and the operating temperature.
