Complete Guide on POM (Polyoxymethylene): Grades, Properties, Applications, and Global Trade
1. What is POM? | Full Form and Overview
POM (Polyoxymethylene), also known as Acetal, is a high-performance engineering thermoplastic known for its exceptional dimensional stability, low friction, high stiffness, and excellent wear resistance. It is commonly used in precision parts requiring low wear and high accuracy.
Other Names: Acetal, Delrin®, Polyacetal, Ultraform®
2. Types and Grades of POM
| Type | Features | Use Case |
|---|---|---|
| Homopolymer POM | Higher crystallinity, better strength | Automotive gears, zippers |
| Copolymer POM | Better thermal and chemical resistance | Pump components, plumbing fittings |
| Glass-Filled POM | Higher stiffness, dimensional stability | Structural parts, electronic housing |
| Lubricated POM | Lower friction coefficient | Bearings, bushings |
3. Key Properties of POM
| Property | Typical Value |
|---|---|
| Density | 1.41 g/cm³ |
| Melting Point | 165–175°C |
| Tensile Strength | 60–70 MPa |
| Elongation at Break | 20–50% |
