Polyether Ketone Ketone (PEKK) is a semi-crystaline thermoplastic in the Polyaryletherketone family. With high heat resistance, chemical resistance , has the ability to withstand high mechanical loads, is inherent flame retardant and has unique tribological properties. PEKK Filament has a tuneable crystallization rate which allows FFF or FDM users to take advantage of both the extreme performance of PAEKs and easier processing of amorphous materials; PEKK Filament is easier to print than regular PEEK filament with a better layer adhesion, while offering similar strength and resistance properties; better dimensional stability. PEKK has a higher Tg than PEEK of 15°C.
