Delrin® POM
ACETAL Homopolymer

Delrin® is the world's first monopoly acetal, with very similar properties to metals, excellent performance between gold and traditional plastics, such as automotive, home appliances, construction, electronics and hygiene products.


  1. Delrin POM is a monomerized/homopolymeric acetal resin. The full name is Polyoxymethylene, abbreviated as POM.
  2. It has a wide operating temperature range of -40°C~120°C.
  3. Delrin has better mechanical strength than other brand copolymer specifications. Izod notched impact strength/ISO 180/1A test standard,Delrin 500PNC010 has values of 9 KJ/m2 and 8 KJ/m2 at 23° C and -30° C, and copolymerization specifications of 5.7 KJ/m2 and 5.5 KJ/m2.
  4. Excellent oil and chemical resistance. Delrin series products for standard fuels, insulating oils, lubricating oils (23°C), diesel (23°C) and ester acids, methanol, ethyl alcohol, isopropanol, toluene, acetone, (di) ether, sodium hydride solutions... etc., with good resistance. For detailed instructions, please refer to the original DuPont factory information.
  5. UL certification is complete, and it is also the certification material for seat belt systems and door systems of major international car manufacturers.
  6. Compared with other engineering plastics, it has better self-lubricating properties and low abrasion characteristics. Taking Delrin 500PNC010 specification as an example, its dynamic friction coefficient (DynamicCOF) is 0.1-0.3m/s speed, and the coefficient is 0.32~0.45 for grinding parts for metal, while the value of PA66-Zytel 101LNC010 is 0.40~0.70.
  7. Most oof standard pass FDA and NSF certified.
