PEEK (Polyether Ether Ketone) is a high-performance engineering plastic used in extreme environments. Typical applications include aerospace components, medical devices, oil and gas parts, electrical insulation, bearings, seals, and precision machined components requiring high strength and heat resistance.

PEEK offers exceptional mechanical strength, excellent chemical resistance, very low moisture absorption, and continuous operating temperatures up to around 250°C. It also has excellent wear resistance, dimensional stability, and electrical insulating properties.

PEEK is significantly stronger, more heat resistant, and more chemically stable than nylon or acetal. It maintains performance at much higher temperatures and under heavier loads. The trade-off is cost — PEEK is substantially more expensive and used only where its properties are required.

Yes. PEEK machines well using CNC lathes and mills, producing accurate, high-quality finishes. Due to its hardness and cost, sharp tooling, correct speeds, and experienced machining practices are essential to avoid waste and tool wear.

Yes. Certain grades of PEEK are suitable for food contact and medical use when supplied with the appropriate certification. It is commonly used in medical implants, surgical instruments, and food processing equipment where high performance and cleanliness are critical.
