Ultraform® W2320 U03 is a very free-flowing, rapidly solidifying, UV stabilized acetal polyoxymethylene (POM) copolymer grade. Exhibits 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. Used where processing is extremely difficult but mechanical properties are lower. It complies with the EU Directive 2006/122/EC (PFOA), EU Directive 2011/65/EU (RoHS) and EC Regulation 1907/2006 (REACH).
