Material Properties

POM (also known as Acetal or by the brand name Delrin®) is one of the most widely used engineering plastics. It combines high mechanical strength with excellent dimensional stability and low moisture absorption.

Available in both homopolymer (POM-H) and copolymer (POM-C) grades, POM offers excellent machinability and is ideal for high-precision components requiring tight tolerances.

Excellent dimensional stability and low creep
Low friction coefficient and self-lubricating
High mechanical strength and stiffness
Excellent machinability to tight tolerances
Good resistance to solvents and fuels
