Product overview

Kepstan® is a Polyetherketoneketone (PEKK) CoPolymer and is in the family of Poly Aryl Ether Ketone (PAEK) polymers. PEKK is synthesized in various formulations with individually unique properties. The PEKK formulations are expressed by the ratio of Terephthaloyl (T) to Isophthaloyl (I) moieties used during the synthesis that created the polymer. The T/I ratio affects PEKK’s melt point glass transition temperature and crystallization kinetics.
