What is PEEK Material?
PEEK (polyetheretherketone) is a high-performance organic thermoplastic polymer with excellent mechanical strength. PEEK material has the ability to maintain stiffness at high temperatures, giving it a proven track record in challenging environments such as aerospace, automotive, and electronics.
PEEK Uses and Material Applications
Peek material properties make it suitable for many different applications. This innovative thermoplastic offers temperature, chemical, and abrasion resistance.
Aerospace
Aircraft parts made of PEEK are chemically resistant to jet fuel, de-icing solutions, steam, salt, water, and hydraulic fluid. PEEK is also lighter than metals, leading to fuel efficiencies.
Automotive
PEEK material can be used in the production of seals and brake components for vehicles. Its resistance to chemicals and strength at high temperatures make it ideal for these applications.
Medical
PEEK has been used as a spinal implant since the 1980s, with efficacy and safety. It is now broadly accepted as a radiolucent alternative to metallic biomaterials.*
Dental
PEEK material is most often incorporated into removable partial dentures. Its excellent abrasion and compressive resistance means it can handle chewing and tearing motions.
Other Uses
Semiconductor machinery components
Bushings, bearings, seals, and back-up rings
Pump and valve components
Food processing machinery components
PEEK Material Properties
PEEK material has excellent strength, hardness, and temperature resistance. It is also radiolucent, meaning it is almost entirely invisible in x-ray photographs and under fluoroscopy. PEEK has a glass transition temperature of around 143 °C (289 °F) and melts around 343 °C (662 °F). Some grades have a useful operating temperature of up to 250 °C (482 °F). It is highly resistant to thermal degradation, as well as to chemicals or water..***
Because of these PEEK material properties, it is an excellent choice for applications from aerospace to biomedical.
Silicon Nitride PEEK vs Conventional PEEK
Silicon nitride PEEK composite combines the unique and beneficial bioactivity of silicon nitride with the familiar fit, feel, and processing properties of conventional PEEK polymer.
This material is produced by compounding an extremely fine particulate form of silicon nitride into an implant-grade PEEK matrix. Subsequent forming operations produce new surfaces with the same enhanced properties as the original stock composite, giving device manufacturers design and process flexibility when working with this material.
Compared with conventional PEEK, silicon nitride PEEK avoids coating delamination concerns since the bioceramic is uniformly dispersed throughout the polymer volume instead of adhered to the surface. In addition to exhibiting comparable mechanical properties to monolithic PEEK, silicon nitride PEEK has demonstrated improved imaging properties along with resistance to biofilm formation and up regulation of bone cell activity during testing in vitro.**
