![]() This material is produced by compounding an extremely fine particulate form of silicon nitride into an implant-grade PEEK matrix. 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. It is highly resistant to thermal degradation, as well as to chemicals or water.***īecause of these PEEK material properties, it is an excellent choice for applications from aerospace to biomedical. Some grades have a useful operating temperature of up to 250 ☌ (482 ☏). PEEK has a glass transition temperature of around 143 ☌ (289 ☏) and melts around 343 ☌ (662 ☏). ![]() It is also radiolucent, meaning it is almost entirely invisible in x-ray photographs and under fluoroscopy. PEEK material has excellent strength, hardness, and temperature resistance.
