Polyetheretherketone (PEEK) - TECAPEEK natural is a high performance, high temperature, semi crystalline thermoplastic manufactured by Ensinger and may use Victrex® PEEK 450 or Solvay‘s KetaSpire® KT-820 polymer. The most well known and important member of the polyaryletherketone group combines excellent wear, and very good mechanical properties, even under thermal load. Outstanding chemical resistance and a high operating temperature (up to 260°C) round out its profile, and make TECAPEEK an almost universally appropriate material for highly stressed parts.
Its excellent dimensional stability combined with high creep stability, supports the suitability of PEEK for the most sophisticated machined parts. Ensinger manufactures PEEK plastics in various shapes such as PEEK rod, PEEK plate and PEEK tube.

As with all Ensinger PEEK materials, we can confirm that TECAPEEK natural meets the limitations imposed by RoHS Directive 2011/65/EU Restriction of Hazardous Substances in electrical and electronic equipment.
