    Delrin® | McMaster-Carr

    Is Delrin a good material?
    Delrin is a good material with greater stiffness, slightly better tensile and impact strength, and a lower coefficient of friction. However, it has internal voids in the material called centerline porosity, which are formed during the manufacturing process.

    Acetal Delrin Sheets & Rods - High Strength, Low Fric…

    Acetal plastic also known as Polyoxymethylene (POM) is an opaque thermoplastic that has high strength, hardness, and rigidity mechanical properties. It is a thermoplastic with high stiffness, low friction, abrasion resistance, and excellent dimensional stability making it ideal for mechanical gears, bearings, rollers, and wear strips. There are 2 g...

    There are 2 general types of acetal thermoplastic; copolymer acetal (POM-C), and homopolymer acetal (POM-H). Delrin is a common name for homopolymer acetal (POM-H) and is a registered trademark of Dupont. POM-C or copolymer acetal is free of centerline porosity which results in a lower coefficient of friction and better impact and wear properties i...
