Acetal (Delrin^®)

Acetal is a highly crystalline thermoplastic with good strength and stiffness, as well as good sliding properties and good wear resistance combined with low moisture absorption. Acetal is dimensionally stable and fatigue resistant and therefor ideal for precision parts. Acetal copolymer is more resistant against hydrolysis, strong alkalis and thermal-oxitive degradation than the acetal homopolymer.

Typical applications include gears, cams, bushings, handles, valves, fittings, impellers, shower heads, toys, zippers and conveyor links.
