PEEK
Polyether Ether Ketone
Polyether Ether Ketone (PEEK) is a very high-performance semi-crystalline thermoplastic offering an exceptional combination of high-temperature performance, mechanical strength, chemical resistance, wear resistance, and biocompatibility (in specific grades).
Typical Grades

Applications

Aerospace & Automotive
Used for high-stress structural parts, metal replacement, bearings, and seals in demanding high-temperature environments.

Medical Implants
Implantable grades are used for spinal fusion devices, joint replacements, and cranial plates due to biocompatibility.

Industrial & Energy
Applied in semiconductor equipment parts, wear components (bearings, seals), valve seats, and wire insulation.
