It is high-flow, 30% glass-fiber reinforced grade of polyetheretherketone (PEEK, engineering plastic). This resin offers higher strength and stiffness properties relative to unreinforced PEEK resin. Reinforcement also affords greater mechanical robustness in structural applications, particularly those with service temperatures approaching 300°C.

It is produced to the highest industry standards and is characterized by a distinct combination of properties, which include excellent wear resistance, best-in-class fatigue resistance, ease of melt processing, high purity and excellent chemical resistance to organics, acids and bases.
