High Performance Polymers

PEKK for SLS - Properties Similar to ULTEM™ Filament*

Materials in this family of polymers are chemical compounds with ether and ketone groups. Compared to other plastics, they have very high glass transition and melting temperatures, which is why they are used in high-temperature applications. PAEK materials are semi-crystalline aromatic polyetherketones with excellent mechanical properties even at high temperatures. They permit continuous operating temperatures of up to 260°C. They are flame-retardant and have high chemical resistance, hydrolysis resistance, high stiffness and strength, as well as very good tribological properties. 

Fields of Application

Thanks to their long service life, PAEK polymers are often used to make high-performance molded parts in industrial contexts, e.g. bearing cages, gearwheels and impellers in pumps and high-pressure systems, especially ones that come into contact with aggressive media. The medical field uses them as a biocompatible material to manufacture sterilizable medical devices or patient-specific implants. They are more cost-efficient than metal implants, and they also avoid some of the associated side-effects, such as sensitivity to the weather. The aerospace industry uses this inherently flame-retardant material as a substitute for metal in the interior and air conditioning systems.
