Polyetheretherketone (PEEK) is a high-performance engineering plastic renowned for its exceptional heat resistance, chemical stability, wear resistance, and mechanical strength. Tailored to meet the rigorous demands of diverse industrial sectors, it serves as a premium raw material for high-stress, high-precision components. Below is its targeted application across core industries:
Aerospace Industry
PEEK’s lightweight and high-temperature resistance (up to 343°C) make it ideal for manufacturing engine parts, avionics housings, and structural brackets. It resists extreme temperature fluctuations and chemical corrosion, reducing aircraft weight while enhancing component durability and safety.
Automotive Industry
For traditional and electric vehicles, PEEK is used to produce wear-resistant engine seals, EV battery insulation components, and sensor housings. It withstands oil, fuel, and coolant corrosion, and its dimensional stability ensures long-term performance in harsh automotive operating environments.
Electronics & 5G Industry
With a low dielectric constant, PEEK is a top choice for 5G communication connectors, PCB substrates, and semiconductor processing equipment parts. Its excellent electrical insulation properties support high-frequency signal transmission, while its heat resistance adapts to the high-temperature working conditions of electronic devices.
Medical Device Industry
Medical-grade PEEK is biocompatible and sterilizable, suitable for surgical instrument components, orthopedic implants, and diagnostic device housings. It matches human bone density, reducing rejection risks, and can withstand repeated sterilization processes without performance degradation.
