Plastic Material: Polyetherketoneketone – PEKK

Polyetherketoneketone (PEKK) is an exceptional semi-crystalline high-performance thermoplastic. Coming from the polyaryletherketone (PAEK) family of polymers, it is recognised for its high-temperature stability and outstanding mechanical strength. Various industries widely regard PEKK as a top-performing material.

Some manufacturers have incorporated carbon fibers into PEKK to further enhance the rigidity and mechanical properties of the material, resulting in a highly robust composite
