Duracon

POM is an acronym for the chemical name polyoxymethylene. It is generally referred to as polyacetal or acetal resin. It is a crystalline thermoplastic resin comprised chiefly of (-CH2O-) structural units.

More Information

The two types of POM are homopolymer, which is comprised of a polyoxymethylene molecular chain made from formaldehyde bonds, and copolymer, in which trioxane, the trimer of formaldehyde, and other comonomers are bonded. DURACON is a representative type of copolymer, and it plays an active role in applications centered on mechanical components such as gears, screws, and bearings.

Characteristics

  1. The material retains well balanced mechanical properties over extended use and a wide temperature range. These properties include tensile strength, elongation, and impact strength.
  2. Superior creep resistance is exhibited over a wide temperature range for extended periods under load.
  3. Exceptional fatigue resistance is possessed. No fatigue is exhibited in use under repetitive stress and continuous vibration, and stable performance is maintained.
  4. High elastic modulus and superior elastic recovery are exhibited, in addition to creep and fatigue resistance, making the material the material of choice by far for springs.
  5. Amongst thermoplastics, the material has the most exceptional friction and wear properties, and exhibits superior tribological properties over extended use. In addition, it is self-lubricating, and used widely in non-lubricated components.
  6. Besides having superior short-term thermal properties such as melting point and DTUL, unrivalled long-term durability is exhibited in hot air and hot water environments.
  7. Dimensional variance as a result of water absorption is minimal, and for all intents and purposes does not present a problem.
  8. Other than acids and chemicals with a strong oxidizing effect, excellent durability with regards to inorganic chemicals and oils is shown.
  9. Possessing superior flowability and beautiful surface gloss, the material has excellent processability. A variety of value-added processes are possible, including insert molding, outsert molding, cutting work, bonding, and printing.

Applications

Examples of its use can be found in AV equipment such as VCRs, CD/laser disk/MD players, radio cassettes, headphone stereos, OA equipment such as printers, keyboards, and CD-ROM drives, home electrical appliances such as washing machines and dryers, and auto parts such as seat belt mechanical components, outer door mirrors, door mirrors, and engine room components, as well as precision components used in such products as cameras and watches, construction materials, toys such as game machines, and stationery.
