Comco-PA 6 C

Polyamide 6 cast (PA 6/c) is a universal material for mechanical engineering applications. It features high mechanical strength combined with sufficient toughness and very good machinability. Its properties can be optimized for specific applications by adding other materials. The casting process allows for a wide range of shapes.

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.

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.

PEEK offers excellent mechanical strength, high chemical and hydrolysis resistance as well as high radiation and steam resistance. The continuous operating temperature of PEEK is about 250 °C. Thanks to its excellent thermal properties, PEEK is suitable for applications at very high temperatures. Its physical properties remain unaffected by the external environment.

Comco-PTFE / TF

The plastic with the highest resistance to chemicals and extremely low adhesion, Teflon / PTFE is a soft sintered material with a low level of mechanical resistance. Its most important properties are: resistance to almost all chemicals, very high continuous service temperature, 260 °C flame retardance, low coefficient of friction, extremely low adhesion, low strength and hardness and high frictional wear.

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.

Comco PA 12 Cast

PA 12 C is a polyamide 12, produced using a monomer casting process. Due to the completely pressureless process, the material becomes highly crystalline and lowtension with a homogeneous, uniform structure throughout. The casting process allows for versatile design.

PLAVIS™ Polyimide

We use this ultra-high-performance plastic based on polyimide to manufacture semifinished and finished parts. PLAVIS™ is characterised by a complex property profile with many outstanding individual qualities – which places it and is thus at the top of our range of plastic materials. It fulfils the most demanding tasks in all areas of industrial electronics, aerospace engineering, transport and the machinery and heavy machinery industries, semiconductor, solar system and flat-screen manufacturing. PLAVIS™ is comparable with Vespel and can be used wherever something must be sealed safely, to minimise wear and friction, to resist high temperatures and harsh operating conditions as well as to save weight.
