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.
PBT
Strong, stiff plastic, excellent machining characteristics, bearing and wear, and chemical resistance.
PCTFE
Fluoropolymer with outstanding dimensional stability, mechanical properties, and temperature range.
PEEK
Strong, stiff plastic with outstanding chemical resistance; performs over a wide range of temperatures.
PET
A strong, dimensionally stable plastic with outstanding chemical resistance and wear properties.
PFA
Flexible fluoropolymer that performs well in extreme temperature and harsh chemical environments.
