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
Material No.: 1701
Density ISO 1183: 1.32 g/cm3
