| About |
|---|
| KEPSTAN™ is a high performance thermoplastic material, based on PolyEtherKetoneKetone (PEKK) highly stable chemical backbone. KEPSTAN™ 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 moieties. The 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 allo w for 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 medium flow grade, KEPSTAN™ 6002, and a high flow grade, KEPSTAN™ 6003, both 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.&& |
