WEB EXCLUSIVE: A comprehensive range of PEKK (polyether ketone ketone), a first from Arkema Inc., King of Prussia, Pa., reportedly stands out from competitive materials because its copolymer structure can be adapted to the requirements of the end-use application. The new Kepstan PEKK range comprises three families of high-performance thermoplastics whose properties meet the requirements of aerospace, oil exploration, and electronics applications:
•Kepstan 6000 are low-melting amorphous grades suited to extrusion and thermoforming, as well as laser sintering and powder coating on metal.
•Kepstan 7000 are crystalline grades for manufacturing thermoplastic carbon-fiber composites, like unidirectional tapes and coated fabrics used in aerospace.
•Kepstan 8000 are crystalline grades that feature top thermomechanical properties and chemical resistance for extrusion and injection molding of components used in ultra-deep oil-well exploration.
