Arkema launches new range of PEKK Kepstan

High performance polymers

Arkema announces a new range of polyetherketoneketone (PEKK) ultra high performance polymers, Kepstan, which meet the requirements of aerospace, oil exploration and electronics applications.

The Kepstan range, developed by researchers at CERDATO, Arkema’s technical polymers research center, is said to compare favorably over metals like aluminum. It comprises three lines of products:

High performance polymers
High performance polymers

Kepstan 6000: low melting point and amorphous grades aptly suited to extrusion and thermoforming, as well as laser sintering and powder coating on metal.Kepstan 7000: optimized grades for the manufacture of thermoplastic carbon fiber composites, like unidirectional tapes and coated fabrics used in aerospace.

Kepstan 8000: grades featuring top thermo-mechanical and chemical resistance properties, for the extrusion or injection molding of components used in ultra deep well oil exploration.

“Thanks to its remarkable thermal and mechanical properties, Kepstan is already well positioned for major civil and military aerospace projects. These sectors are constantly seeking lighter and stronger materials, and our products offer a perfect fit these demanding specifications,” stated Richard Audry, in charge of PEKK development at Arkema.
