KEPSTAN^® 6001

KEPSTAN® PEKK is a unique member of the PAEK family that incorporates distinctive structural features that allow for exceptional possibilities in the control of crystallinity. These features include a low Ether/Ketone ratio and a copolymer structure incorporating Terephtalic and Isophtalic patterns. Its semi crystalline structure in solid state offers an outstanding combination of mechanical and thermal strength and an excellent chemical and fire resistance, with a reduced melting temperature (decreased by 25°C compared to PEEK) and a Tg above 160°C. The KEPSTAN® 6000 Series represents the pseudo-amorphous products of the KEPSTAN® family, offering the lowest melting point and the slowest crystallization behavior, while keeping Tg close to 160°C. These properties allow lower processing temperatures (as low as 320-330°C) and lead to glassy or semi crystalline structures, depending on processing technologies and cooling conditions. KEPSTAN® 6000 Series includes a high viscosity grade, KEPSTAN® 6001, a medium flow grade, KEPSTAN® 6002, and two high flow grades, KEPSTAN® 6003 & KEPSTAN® 6004, all unfilled PEKK resins designed to meet the requirements of a broad range of processing technologies, including among others extrusion, calendering, thermoforming, injection molding, fiber impregnation, rotomolding, powder coating, bonding and welding.
