| 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. KEPSTAN™ 8010C30 is a carbon fibre reinforced compound, based on the 8000 series of KEPSTAN™ resins. This series offers the highest glass transition temperature and the highest crystallinity, leading to the best tensile and compression strengths among the different series of KEPSTAN™ PEKK copolymers. KEPSTAN™ 8010C30 is a low flow grade, suitable for extrusion, compression and injection moulding. KEPSTAN™ 8010C30 is available in pellet form, and standard packaging is 10 kg boxes.&& |
