Ultraform® N2770 K

Ultraform® N2770 K is an acetal polyoxymethylene (POM) copolymer grade reinforced with chalk. Exhibits enhanced wear behavior, high rigidity, strength & stiffness, low water absorption, good resilience properties, low tendency to creep, excellent resistance to fuels & chemicals, excellent sliding friction properties, good long-term thermal stability, impact resistance, good electrical insulation properties and dimensional stability. It is insoluble in water. Can be processed using injection molding. Recommended for sliding parts. It complies with the EU Directive 2006/122/EC (PFOA), EU Directive 2011/65/EU (RoHS) and EC Regulation 1907/2006 (REACH).
