ACETAL COPOLYMER TECAFORM
Tecaform™ is a semi-crystalline thermoplastic offering high strength, stiffness, and toughness. Tecaform™ 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
