Ceramic-modified PEEK (polyetheretherketone) is a composite material that enhances the properties of PEEK by incorporating ceramic particles (such as silica, alumina, or silicon carbide). This modified material combines the excellent properties of PEEK with the high hardness, wear resistance, and high-temperature resistance of ceramics, making it widely used in demanding industrial applications.
Characteristics of Ceramic-Modified PEEK
1. High Wear Resistance:
Ceramic particles significantly improve the wear resistance of PEEK, making it suitable for high-friction environments.
2. Enhanced Mechanical Properties:
Higher hardness, rigidity, and compressive strength.
3. High-Temperature Resistance:
Maintains stable mechanical performance at elevated temperatures.
4. Chemical Resistance:
Excellent resistance to acids, alkalis, solvents, and other chemicals.
5. Low Friction Coefficient:
Ideal for sliding parts and bearings.
6. Biocompatibility**:
Suitable for medical applications, such as orthopedic implants.
