Duracon / Celcon, acetal co-polymer is the most well balanced resin in terms of mechanical, chemical and thermal properties. Further its self-lubricating property and superior mouldability allows it to be widely employed in various industrial fields as one of the most popular engineering plastics.
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 (-CH2-0-) structural units.

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 application centered on mechanical components such as gears, screws, and bearings.

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.
