Material Data Sheet
Material: Tecaform™
Acetal CopolymerTecaform™ is a semi-crystaline 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 available in natural and black grades. Tecaform™ is commonly used in bushing, rollers, wear strips and other applications requiring a combination of strength, low moisture absorption, chemical resistance and dimensional stability. Offers no cernterline porsity and excellent machinability.
