Polyoxymethylene (Acetal / Delrin®)
POM is a high-performance engineering plastic known for its excellent dimensional stability, low friction, and outstanding wear resistance. The go-to material for precision gears, bearings, and mechanical components.
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.

POM's combination of strength, stiffness, and low friction makes it the preferred choice for precision mechanical components across numerous industries.
Precision gears, timing pulleys, and sprockets for mechanical power transmission.
Plain bearings, bushings, and wear pads for low-friction applications.
Clips, fasteners, and safety-critical components in automotive and consumer goods.
FDA-compliant conveyor parts, guides, and components for food machinery.
Impellers, valve bodies, and wear components in pump and valve systems.
Insulators, connectors, and precision components in electrical assemblies.
We supply POM in both homopolymer and copolymer grades, including specialty variants with enhanced properties (glass-filled, PTFE-modified, FDA-compliant).
