POM (Polyoxymethylene)

POM (Polyoxymethylene): High-quality mechanical properties at a low price

Polyoxymethylene (short: POM) is a typical thermoplastic material characterized by the following properties:

great hardness, high rigidity and strength
high abrasion resistance with good sliding properties
low water absorption

More detailed information on this high-performance plastic can be found on our lexicon pages on polyoxymethylene. In addition, you can learn about the most important advantages of polyoxymethylene (POM) and how Sattler SMC can help you realize your next project.

POM can meet high requirements for dimensional stability and a high-quality appearance

Polyoxymethylene can justifiably be called the light metal among plastics. Its outstanding mechanical properties are in no way inferior to those of a metal. However, POM is both lighter and more economical to produce and process than metallic materials.

The outstanding mechanical properties of POM include:

high strength, impact strength and stiffness
excellent wear and abrasion resistance
high long-term maximum application temperature of 110 °C
low water absorption (at saturation 0.8 %)
complete colorability

Due to these properties, polyoxymethylene can be used above all to manufacture components subject to high stresses, which must have a long service life and high robustness at a comparatively low price.

The plastic demonstrates its advantages particularly in thin-walled precision parts

Its hardness and comparatively low weight make POM a versatile material. It is used, among other things, in mechanical components such as gear wheels, counter parts, control discs, impellers, bearings, and sliding and spring elements. POM is also widely used in hydraulic systems. There it is used in pump parts, valve bodies, snap elements or bearing cages.

Since polyoxymethylene, like all plastics, is an excellent electrical insulator, it is also used in the electronics industry and electrical engineering. Here, for example, coilformers, insulators, relays and transformer housings are made of polyoxymethylene.

This range of applications suggests that polyoxymethylene is used in a wide variety of industries:

in mechanical engineering - e.g. gear wheels, slipping clutches or plain bearings
in the automotive industry - e.g. for fixing cable harnesses
in the textile industry - for the production of zippers

POM can be used in the food industry, but special legal regulations regarding hygiene must be observed.

POM can be easily adapted to individual applications

Polyoxymethylene is a high molecular weight thermoplastic that appears opaque white when uncolored. Like all thermoplastics, it can be formed when heated. Workpieces made of POM can be manufactured by the following processes:

Injection molding
extrusion
Blow molding

POM can only be bonded after pretreatment with epoxy resin; welding is recommended for a permanent bond. Machining techniques such as drilling or screwing are also possible.

In a vacuum, POM surfaces can be metallized, painted, flocked or laser-marked.

Rely on our many years of expertise in the production of workpieces made of POM.

As a traditional company for plastics manufacturing and processing, Sattler SCM has both many years of expertise and cutting-edge know-how on high-quality polymers. We accompany you from your sketches and ideas to the finished workpiece. Since we have complete control of the manufacturing and production process at all times, we can intervene in the production process at any time and regulate it if necessary. In doing so, we demonstrate the same care in the design of a single prototype as we do in the development of entire large-scale production runs. Challenge us and contact Sattler today.
