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.
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 (decreased by 25°C) and a Tg above 160°C, the KEPSTAN 7000 Series resins are highly enabling in the field of continuous fiber composites for structural applications.
