Polyetherketoneketone (PEKK) is a semi-crystalline thermoplastic in the polyaryletherketone (PAEK) family of polymers. It possesses high heat, chemical, and mechanical load resistance.[1] PEKK has a glass transition temperature (Tg) of 162 °C.[2]
Applications[]
Oxford Performance Materials manufactures PEKK-based parts for Boeing for use in its Starliner space taxis, using 3D printing-based additive manufacturing. It has wide dental and medical applications.[3] The parts are claimed to be as strong as aluminum while being 40 percent of the weight. In addition, PEKK manufactured components have shown fire and radiation resistant properties.[4]
