Polyetheretherketone (PEEK) is rigid and flexible, especially for its fatigue resistance under alternating stress, which is comparable to alloy materials.  Self-lubricating PEEK has excellent sliding properties and is suitable for applications requiring low friction coefficient, especially for PEEK modified with carbon fiber, and graphite carries excellent wear resistance.  In addition to concentrated sulfuric acid, PEEK is insoluble in any solvent, strong acid, and alkali, and has high chemical stability.  Flame-retardant PEEK is self-extinguishing and can satisfy UL standard 94V-0 without any filling of flame retardant.

Due to its excellent comprehensive properties, polyetheretherketone (PEEK) can replace traditional materials such as metals and ceramics in many special fields.  PEEK's high temperature resistance, self-lubrication, wear resistance and fatigue resistance make it one of the hottest high performance engineering plastics today, mainly applied to the fields of aerospace, automotive, electrical and electronic and medical devices.

     1. Aerospace

Polyetheretherketone (PEEK) can be processed into a variety of high-precision aircraft parts. Due to its resistance to hydrolysis, corrosion and flame retardancy, it can be made into lots of internal and external parts of the aircraft and rocket engines.

 2. Automotive

Polyetheretherketone (PEEK) has the good abrasion performance, and can replace metal, including stainless steel and titanium, for manufacturing the engine hood, automotive bearings, seals, brake pads, etc..

     3. Hardware & Machinery

Polyetheretherketone (PEEK) has good mechanical properties, including high temperature resistance, wear resistance, and high pressure resistance.  It is commonly used to manufacture compressor valves, piston rings and seals, etc..

     4. Medical Device

Polyetheretherketone (PEEK) can withstand 3,000 cycles of autoclaving at 134 °C.  Its creep and hydrolysis resistance is commonly used in a variety of manufacturing of medical devices, surgical and dental equipment requiring high temperature steam sterilization. 

In addition, PEEK is non-toxic, light weight, and corrosion resistant, and is the closest material to the human skeleton.   Therefore, PEEK can be used instead of metal to make human bones.

     5. Semiconductor

Polyetheretherketone (PEEK) has superior electrical insulation properties.  At high temperature, humidity and other harsh conditions, it can still maintain its insulating properties.  It is preferably electrically insulating material, widely used in the semiconductor industry.
