PEKK

PEKK (Polyetherketoneketone) filament is a premium high-performance super engineering material related to PEEK. It offers excellent high-temperature resistance, high mechanical strength, low flammability, good chemical resistance and excellent dimensional stability. Lower crystallization speed makes it easier to print than PEEK while retaining similar properties. Requires very high nozzle temperature and enclosed high-temperature chamber. Suitable for aerospace structural parts, medical components, high-load bearings and high-temperature industrial parts.
