Polyetheretherketone

High-temperature plastic with excellent mechanical properties.

Resistant to hydrolysis and hot steam of above + 260 °C. It isolates electrically even at high voltages. Possibility of high mechanical resistance even at high temperatures. Intermittent use up to + 300 °C. Excellent stability to chemicals, good slip properties, gamma-radiation and creep resistance, can be sterilized.

We process the materials using the following procedures:

Extrusion: Extruded profiles according to drawings and semi-products according to DIN.

Machine parts: Turned and milled parts in single and serial production.

Pressings: Injected moulded parts weighing up to 16.000 g
