Introduction of POM
Polyoxymethylene (POM), commonly known as acetal or Delrin, is a high-performance engineering thermoplastic with a wide range of applications due to its exceptional mechanical properties and versatile processing capabilities. POM is characterized by its low coefficient of friction, high stiffness, excellent dimensional stability, and resistance to wear and creep. It is often chosen for applications that require precision, durability, and resistance to moisture and chemicals.
Price: High-range of plastic material costs
Application: gears, bearings, sliding components, automotive parts, medical devices, and consumer goods, etc.
Recommended Wall Thickness: 1mm-3mm
POM is synthesized from formaldehyde through a polymerization process, resulting in a linear polymer structure with repeating -CH2O- units. This structure contributes to its remarkable properties. Here are the general POM properties.
