Polyetheretherketone
Brand: Sustapeek® — Röchling
Standards: ISO 10350, ASTM D6779
PEEK (Polyetheretherketone) is the premium high-performance thermoplastic. It offers exceptional mechanical properties at temperatures up to 250°C, excellent chemical resistance and inherent flame retardancy (V0). Used in aerospace, medical, semiconductor and oil & gas applications where other plastics fail.
