Aerospace: Used for components like bearings, seals, and insulating parts due to its lightweight nature, high strength, and ability to withstand extreme temperatures.

Automotive: Applied in engine parts, gears, and transmission components that require durability, chemical resistance, and high-temperature performance.

Medical Devices: Utilized in surgical instruments, implants (such as spinal cages and bone fixation devices), and dental applications due to its biocompatibility and sterilization resistance.

Oil & Gas: Suitable for seals, valves, and compressor plates that require excellent resistance to aggressive chemicals and high temperatures found in harsh environments.

Electronics: Used in connectors, insulators, and circuit boards because of its excellent electrical insulating properties and high-temperature stability.

Semiconductor Manufacturing: PEEK components are employed in semiconductor fabrication equipment where low particle generation, chemical resistance, and mechanical strength are essential.

Chemical Processing: Applied in pumps, seals, and gaskets in chemical plants due to its resistance to solvents, acids, and bases, as well as its ability to function in high-pressure environments.
