Technical plastics represent about 20% of the worldwide plastic production. The qualities of these materials exceed those of standard plastics which leads to a higher price as a consequence.
he intended utilization of technical plastics is not for optical or haptic purposes, but only for technical applications.
Technical thermoplastics are usually able to bear temperatures up to 130°C. They are particularly characterized by high durability, good viscosity and shock absorption as well as by a usually good processing and a balanced cost-benefit ratio.
Technical plastics (PA, POM, PC) are used for all application types. As a consequence, slide bearings, rollers and wheels or sealings as well as formed parts, isolators or housings and workpiece supports are made of these materials.
Many traditional materials like metal components are more and more replaced by high-quality plastics thanks to their known advantages like, for example, good abrasion resistance, no corrosion, excellent sliding characteristics, high durability, good chemical resistance, dimensional stability as well as high temperature stability.

milled part made of POM
POM is used as technical plastic material especially for precision parts due to its high rigidity, low frictional coefficient and excellent dimensional stability.
Difference is made between homopolymeres (POM-H) and copolymeres (POM-C). Owing to their higher crystallinity, homopolymeres have a slightly higher density, durability and solidity. In contrast, copolymeres have a higher impact resistance, better abrasion resistance as well as better thermical and chemical stability.high durability, rigidity and solidity.

Polyamides are partially chrystalline. Synthetic polyamides possess a high solidity, rigidity and a very good chemical resistance. Moreover, their stability to wear and tear is high and their sliding characterisitcs are good as well. The mechanical qualities can be adjusted easily by means of fibre compounds with glass or coal fibres and, consequently, hydrolysis can be reduced. Furthermore, the relatively high water absorption of up to three percent by mass can be reduced.
