Polyacetal or Polyoxymethylene is a semi-crystalline engineering thermoplastic widely used to produce high precision parts thanks to high lubricity. Discover how it is manufactured, what are the various types of POM available (homopolymer and copolymer) and its key properties ranging from mechanical, physical and chemical. This resin is an ideal material of choice in applications ranging from automotive to medical, industrial and many more.

It is a formaldehyde-based, semi-crystalline engineering thermoplastic which contains the functional group of a carbon bonded to two -OR groups. It is 100% recyclable. POM is known as polyformaldehyde, polymethylene glycol and polyoxymethylene glycol.

Applications for POM include high performance components such as gear and fasteners (screws, nuts, washers, spacers, etc.). It is also used in other applications such as ski bindings, yoyos, electronic cigarettes, watch bracelets, zippers, insulin pens, and metered dose inhalers. It is used in musical instruments for picks and instrument mouthpieces, in the food industry in applications like milk pumps and coffee spigots, and also as a solvent for perfumes and as a synthetic flavoring ingredient.
