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.
