POM (Polyoxymethelene)

 
Formula chimica POM

Polyoxymethylene (POM) also known as acetal resin or polyformaldehyde is a crystalline thermoplastic polymer. It is used where excellent dimensional stability, low friction and high resistance are required. Repeating chains are composed of a methylene group and an oxygen atom. The material is very resistant with a relatively low cost. It has a very low friction coefficient and excellent thermal resistance.

Chemical formula POM: (CH2O)n
CAS Number POM: 9002-81-7
Chemical Name POM (IUPAC): poly(oxymethylene)
Recycling Code POM: number 7
Recycling Symbol POM: simbolo riciclo POM

Chemical and physical properties:

POM is used a lot for its excellent mechanical characteristics. It has an excellent creep resistance, low friction, and excellent performance at low temperatures. However, chemically it has some disadvantages such as easy combustion and the production of toxic fumes which consequently severely limit its field of use. POM is divided into two main categories, POM homo, and POM copo which differentiates itself from the former by the presence of groups –CH2CH2O–.

POM standard density: 1,35 - 1,44 g/cm3 (ISO 1183)
POM melting point Tm: 165 - 185 °C
POM glass transition temperature Tg: -50 °C
