Greene Tweed provides precision-molded thermoplastic composite components made from our high-performance Orthtek® material for a variety of demanding medical and biotechnology applications. Orthtek®’s high strength, low weight, corrosion resistance, and dimensional stability for steam or autoclave sterilization make it a high-performance metal replacement. Orthtek® is also radiolucent for X-ray transparency.

Depending on the application, Greene Tweed also has elastomers with the capability to be overmolded on metal and thermoplastic composites for custom medical devices.

Orthtek® composites have a PEEK polymer matrix with high carbon fiber reinforcement content (50% fiber volume), and are available in different material forms, as shown:

Orthtek® BF

  • Braided fabric; braided into near-net molded shapes with oriented reinforcement fiber

Orthtek® RP

  • Discontinuous (random) fiber reinforcement for complex shapes

Orthtek® WF

  • Woven fabric reinforcement
  • Also available as stock shape plates up to 1.5 inches thick
