Barlog Plastics KEBAFORM C 25 H Wear Resistant POM-C
Categories: Polymer; Thermoplastic; Acetal (Polyoxymethylene, POM); Acetal Copolymer, Unreinforced

Material Notes: KEBAFORM C 25 H is a new type of POM that has been specially developed for sliding and wear applications. Compared to a standard POM copolymer, the material is characterized by a higher crystalline structure and thus better wear properties and a higher melting temperature. The improvement in the sliding and wear behavior of KEBAFORM C 25 H is achieved solely by modifying the polymer chain and thus there is no reduction in the mechanical properties due to the addition of tribologically effective additives. Due to its property profile, KEBAFORM C 25 H is particularly well suited for applications that require good sliding and wear behavior but do not allow any compromises in mechanical properties, e.g. for gears, rollers, plain bearings, guide bushes, etc.

Properties: dimensionally stable, good chemical resistance, good gliding properties, good recovery behavior, High wear resistance, semi-crystalline
