Thermoplastic semi-finished products

Comco-POM-C

This semi-crystalline thermoplastic features good frictional properties and high dimensional stability. POM-C offers high mechanical load-bearing capacity paired with good machinability. For all customers requiring mechanically precise components and strict tolerance ranges, our POM-C is highly recommended. Thanks to its low moisture absorption, POM-C is suitable for components that must function underwater or in a wet environment – humidity does not change its properties. POM-C is also resistant to a wide range of organic solvents and chemicals.

Comco-PET

Alongside POM-C and PA6 casting, PET (or PET P) is one of the most widely-used technical plastics. Its excellent mechanical properties make it ideal for applications like precision mechanical components. PET offers high tensile strength and mechanical load-bearing capacity, stable hardness and good dimensional stability. Because of its low coefficient of friction, Comco PET is frequently used for components demanding high wear resistance such as wear parts, bearings, bushings, turntables or track rollers. PET is also suitable for applications in the food processing industry requiring high chemical resistance and low moisture absorption.

Comco PA 6.6

Compared to PA 6, PA 6.6 has a slightly higher surface hardness and rigidity, as well as reduced moisture absorption. Further positive features include increased wear and heat resistance, but it has a lower toughness compared to PA 6. One popular modification is the 30% glass fibre reinforcement. PA 6.6 GF 30 features increased dimensional stability, very high rigidity and even greater heat resistance compared to unreinforced versions.
