SUSTAPEEK – sheets, round rods & tubes / tubing

PEEK (Polyetheretherketone) – properties & applications

We process the high performance plastic PEEK (Polyetheretherketone) under the brand name SUSTAPEEK as semi-finished products in the form of sheets, round rods and tubes as well as machined components.

PEEK (Polyetheretherketone) is a semi-crystalline, thermoplastic high-performance material, and is characterised mainly by its very good mechanical properties and exceptional dimensional stability, even at high continuous operating temperatures of up to 250°C. Due to their properties, PEEK plastics are suitable for a wide range of applications with demanding operating conditions

Product range – SUSTAPEEK:

SUSTAPEEK is available as a semi-finished product in numerous dimensions and colours:

  • PEEK sheets
  • PEEK round rods
  • PEEK tubes / tubing

We also offer machined components on the basis of customer drawings made from PEEK and cut-to-size PEEK.
