KEPSTAN™ is a high performance thermoplastic material, based on PolyEtherKetoneKetone (PEKK) highly stable chemical backbone. Its semi crystalline structure in solid state offers an outstanding combination of mechanical and thermal strength together with chemical and fire resistance.
Among the KEPSTAN™ family, the 7000 Series benefits uniquely from PEKK crystalline capabilities while reducing significantly processing temperatures compared to the more crystalline 8000 Series. With a reduced melting temperature (Tm decreased by 25°C) and a Tg above 1 60°C, the KEPSTAN™ 7000 Series resins are highly enabling in the field of continuous fiber composites for structural applications.
KEPSTAN™ 7000 Series includes a medium flow grade, KEPSTAN™ 7002, and a high flow grade, KEPSTAN™ 7003, both unfilled PEKK resins designed to meet the requirements of a broad range of melt processing technologies, including among others extrusion, injection molding, fiber impregnation, consolidation and composite forming technologies.
KEPSTAN™ is available in pellet form and in powder form with different particle sizes. Standard packaging includes 20 kg boxes for pellets and 10 kg boxes for powders.
