PEEK (Polyether Ether Ketone) is a high-performance thermoplastic polymer in the PAEK (Polyaryletherketone) family. Offering high radiation resistance, excellent electrical insulating properties, and resistant to biodegradation, it’s another highly sought after material suitable for demanding applications across various industries.
PEEK offers high tensile strength (##-### MPa), Young’s modulus of 3.6 GPa, and excellent creep resistance and dimensional stability
PEEK provides a glass transition temperature of 143C (289F), a melting point of 343C (649F), and useful operating temperature of up to 250C (482F).
PEEK material has high resistance to thermal degradation and low moisture absorption (0.1% over 24 hours)
PEEK has a high level of resistance to harsh chemicals including solvents, acids, bases, and oils. PEEK is one of the few thermoplastics that can withstand concentrated sulfuric and nitric acids.
PEEK also has high radiation resistance, electrical insulating properties and is resistant to biodegradation, resulting in the use of PEEK in the reserved case of critical applications.

Discover how PEEK thermoplastic is used today
Used in automotive components including bearing cages, thrust washers and seals, pump components like impellers and housings, and gear parts. Excellent wear resistance, dimensional stability at high temperature, and chemical inertness make it perfect for automation applications.
Aerospace/aviation components including bearings, piston parts, and pumps, radomes and antenna housings, along with wire insulation and cable ties. A preferred material in aerospace due to its lightweight, high-strength to weight ratio, and resistance to harsh chemicals like jet fuel and de-icing liquids.
Medical and surgical components, devices and equipment from spinal cages and hip joints to catheters and dental materials. Properties including PEEK biocompatibility, sterilizability, and X-ray transparency make it ideal for medical instrumentation and implants.
