Due to their special characteristics, polyoxymethylenes - also known as POM - are among the most essential construction materials in the manufacturing industry. The following text provides an overview of the most important characteristics of the plastic, its uses and applications. You will also learn what Müller Ahlhorn uses this versatile construction material for. 

What are polyoxymethylenes?

Polyoxymethylene is a plastic that belongs to the class of thermoplastics. Due to its individual properties, polyoxymethylene is a very frequently used material in the field of plastics processing. Polyoxymethylene has good to very good rigidity, excellent tensile strength and outstanding impact strength. Polyoxymethylene also has exceptionally good sliding and abrasion properties. 

Since the plastic also absorbs practically no water and is very resistant to chemicals, it is used in a wide variety of applications and constructions. Polyoxymethylene tolerates temperatures from - 45° to 80° Celsius. It can even be exposed to temperatures of up to 120° Celsius for short periods without losing its shape and strength. 

How are polyoxymethylenes processed and used?

POM is processed in many different ways in industry. The main processing methods include injection moulding, welding, extrusion and machining. Polyoxymethylenes are extremely resistant and hardly wear out even under continuous stress. The spectrum of applications ranges from gear parts, pump elements and window handles to ski bindings, snap elements and impellers. 

Polyoxymethylene can be used to produce dimensionally stable and dimensionally stable structural parts for a wide range of industries. The plastic is used with great success in the automotive industry, textile industry and medical technology, among others. 

However, the most important areas of application for polyoxymethylene are

  • Electrical industry and
  • Car industry

Compared to other plastics, POM is more versatile. The plastic has largely replaced PA6, which was frequently used in the past, as it absorbs less water than PA6. Polyoxymethylene can also be bonded - but only after prior treatment. Also interesting: 

There are two different types of polyoxymethylene: 

the somewhat denser and stronger polyoxymethylene-H and 

the somewhat more abrasion-resistant and impact-resistant polyoxymethylene-C. 

Which polyoxymethylene is used always depends on the respective requirements.
