Acetal Products (ZL® 900 series)

Acetal Copolymer (POM-C) offers much less centerline porosity compared to that of
acetal homopolymer. As compared to acetal homopolymer, acetal copolymer offers superior hot
water resistance; more resistance to strong alkalies and thermal-oxidative degradation; improved
impact resistance and much lower outgassing.
Acetal Homopolymer (POM-H) is most commonly known by the E.I. Dupont trade name Delrin®. It offers higher crystallinity than copolymer acetal. Homopolymer acetal is harder, stronger, improved mechanical strength, stiffness, creep resistance and also has a lower thermal expansion rate than copolymer acetal.
Fast fact: Acetal provides excellent dimensional stability and is ideal for wear applications in wet
environments.
