Polyacetal/Delrin

Material Overview

Polyacetal (also known as Delrin or POM) is a high-quality engineering thermoplastic with excellent mechanical properties. It combines high strength and stiffness with low friction and very good dimensional stability. Due to its wear resistance, chemical resistance, and temperature resistance, it is widely used as a metal substitute in technical components. Ideal for laser cutting and engraving where precision and durability are key.
