Physical Properties

Typical Applications

Structure

Partially crystalline
Different manufacturing processes are used to produce the homopolymer and copolymer versions of POM.

Identification

Highly flammable, gives off a bluish flame and then drips and continues to burn. Smells like formaldehyde when extinguished.

Useful data

Pre-Drying – Not necessary unless it has become moist. Then 4 hours at 100°C in a dehumidifying hot air drier Melt temperature – 205-215 °C Mould Temperature – 40-120 °C Shrinkage – Approx 2 %. Allow 24 hours for full shrinkage to occur.

History

The worlds first Acetal polymer was introduced in 1960 by DuPont and was named Delrin ®. It is widely used in many different applications today such as automotive, industrial, electronic and consumer goods.

Delrin® is the registered trademark for DuPont’s brand of acetal homopolymer resin which is also commonly referred to as polyoxymethylene (POM).

Around two years later in 1962, Polycetal copolymer was invented by Celanese. Many other companies around the world now produce this material.
