Medical grade PEEK composite


TECATEC PEEK MT CW50 black is a carbon fibre composite material characterised by extraordinary mechanical strength and high thermal dimensional stability.

The fields of application are very often within traumatology, with applications like internal fixation systems (target arms), external fixation systems as well as other structural elements.



TECATEC PEEK MT CW50 black meets the specified requirements of the biocompatibility testing according to standard ISO 10993-1, -4, -5, -18 for contact of up to 24 hours with skin and tissue and, if applicable, indirect contact with blood.

Key characteristic

Ensinger's carbon fibre reinforced composite material consists of a thermoplastic matrix and carbon fibre fabric bundles. This combination ensures significantly higher tensile and flexural strength compared to fibre-reinforced extruded materials. The material's high glass transition temperature of 143°C, low water absorption and excellent chemical resistance result in very good sterilisation resistance and high thermal dimensional stability.
Other properties include

  • excellent strength
  • excellent heat resistance
  • Low water absorption
  • Corrosion resistance
  • excellent resistance to superheated steam autoclaving
  • Exceptional chemical resistance

Our TECATEC PEEK MT CW50 black is also radiopaque, allowing unrestricted x-ray imaging of the surgical site despite the target device being attached. Due to their low specific weight, products made from TECATEC materials are easy to handle and therefore ergonomically effective.

Hot steam sterilisation

By using TECATEC materials, a long service life of the corresponding products in the hospital can be achieved.  Very good sterilisation resistance to superheated steam enables a high number of possible sterilisation cycles, in some cases over 500 cycles, and thus reduces maintenance costs as well as replacement costs.

TECATEC MT Materials

The PEEK polymer used in TECATEC PEEK MT CW50 black is VICTREX PEEK, a densified polymer with carbon fibre fabric. A special coating on the fabric reduces the number of defects. The 50% carbon content provides extreme torsional rigidity and virtually eliminates warping, even with repeated sterilisation.

TECATEC PEEK MT CW50 black is manufactured to customer specifications, focusing almost exclusively on customer size requirements. Ensinger offers TECATEC PEEK MT CW50 black in sheet thicknesses in 1 mm increments to maximise material and cost savings.
