Plastic
PEEK, short for Polyetheretherketone, is a high-performance thermoplastic with excellent mechanical and chemical properties, combined with a high melting point and low wear. This material performs even at high temperatures and under heavy loads.
Well-known trade names for PEEK include: Victrex® PEEK, Solvay Ketaspire® PEEK and Evonik Vestakeep® PEEK.
These properties make PEEK the material of choice for demanding applications in aerospace, medical technology, and the oil and gas industry. Alternatives include PPS (Polyphenylene Sulfide) or PEI (Polyetherimide).

PEEK has a much higher melting point (343 °C), superior mechanical strength and chemical resistance, making it ideal for extreme conditions.
Yes, PEEK can be supplied biocompatible and is widely used for implants and surgical instruments.
PEEK machines well by milling, turning, laser cutting and 3D printing. Post-processing can include polishing or smoothing saw cuts.
PEEK is a high-end polymer with higher material costs than PA or PP, but its longer service life and performance often justify the premium.
Without additives, PEEK may discolor after prolonged UV exposure; UV-stabilized grades remain highly weather-resistant.
PEEK is a thermoplastic and can be recycled, but processing must be controlled to avoid contamination.
Yes, PEEK resists most acids, bases and organic solvents even at elevated temperatures.
For higher temperature demands, ceramics or high-performance metals (e.g., Inconel alloys) are often more suitable.
