Polyacetal - POM (PolyOxyMethylene) is a high crystalline thermoplastic with a high level of stability and rigidity as well as good sliding properties and wear resistance with a low level of moisture absorption. Its good dimensional stability, exceptional fatigue resistance and excellent machining properties make Polyacetal a versatile design material also for complex components. It satisfies high surface finish requirements and offer better surface hardness, toughness and excellent solvent and gasoline resistance.

A High Degree of crystallinity makes acetals stiffer and stronger than most thermoplastics, yet they are tough at ambient and low temperature, good dimensional stability is a key property.

Acetals absorb little water, minimizing its effect on their physical properties.

There are two basic types of acetal resins; Homo-polymer and Copolymer.

The homo-polymers’ strength properties tend to be slightly higher than those of the copolymers. Delrin is a homo-polymer Polyacetal. Delrin has higher (short term) heat deflection temperatures than copolymers, but their continuous use temperature is 85°C (185°F) compared to 100°C (212°F) for copolymers. The homo-polymers tend to have somewhat greater surface hardness, higher degree of density and a slightly lower coefficient of friction.

The copolymers, compared to homo-polymers, tend to absorb less water, are more resistant to hydrolysis and have superior processing characteristics. Copolymers, however, have higher impact toughness, greater wear resistance and thermal / chemical resistance.

Acetals are mostly used in applications where excellent surface finish & accuracy with good dimensional stability are required. These are also preferred as a good material for food & pharmaceutical, chemical & oil industries.
