This pom acetal polyoxymethylene guide explains practical material, design, manufacturing, and sourcing considerations for Nylon Plastic readers.


What Is POM Acetal Plastic?

POM (Polyoxymethylene), also known as acetal or Delrin, is a highly crystalline engineering thermoplastic. Its combination of high stiffness, low friction, and excellent dimensional stability makes it ideal for precision mechanical components.
Key Properties of POM
- Tensile Strength: 60–70 MPa
- Flexural Modulus: 2,500–2,800 MPa
- Melting Point: 165–175°C
- Coefficient of Friction: 0.2–0.35
CNC Machining Best Practices
Use sharp carbide tools, 150–250 m/min cutting speed for turning, and air blast or flood coolant.
Common Applications
Gears, sprockets, bearings, bushings, guide rails, food processing equipment, and medical device components.
