POM or Polyacetal or Delrin – are the commonly referred names for Polyoxymethylene, which offers more freedom in application engineering. The highly crystalline structure of POM offers an outstanding combination of physical properties:

Polyacetal sheets, plates  are among the strongest and stiffest of all thermoplastics. Polyacetal and Delrin plastic materials are characterized by good fatigue life, low moisture sensitivity, and high resistance to solvents and chemicals.
