ACETAL COPOLYMER
Acetal Copolymer is a semi-crystalline thermoplastic offering high strength, stiffness, and toughness. The material is resistant to hot water, hydrocarbons, and solvents, and it possesses good bearing and wear properties. It is commonly used as bushings, rollers, wear strips and other applications requiring a combination of strength, low moisture absorption, chemical resistance, and dimensional stability. Additional attributes include: No centerline porosity, good dimensional stability, low moisture absorption, good wear and abrasion properties, excellent machinability
