POM - Acetal Polyoxymethylene
TECAFORM Ensinger Plastics
POM material, commonly called acetal (chemically known as Polyoxymethylene) is manufactured by
Ensinger in standard stock shapes for machining and is extruded in sheet, rod and tube. POM
plastic is a semi crystalline thermoplastic with high mechanical strength and rigidity. Acetal polymer
has good sliding characteristics and excellent wear resistance, as well as low moisture absorption.
The good dimensional stability and particularly good fatigue strength, as well as excellent
machining ability, makes POM polymer a highly versatile engineering material, even for complex
components.
A distinction is made between acetal homopolymers (POM-H) and acetal copolymers (POM-C) in
regard to their properties. Due to its higher crystallinity, the properties of POM H include a slightly
higher density, hardness and strength. POM C material, however, has higher chemical resistance
and a lower melting point than POM H.
