1. Low density: It is of great significance to reduce the weight of mechanical equipment and save energy, especially for vehicles, ships, aircraft, and spacecraft.
2. High specific strength and specific stiffness: PEEK has low density, and relatively high specific strength (σb/ρ) and specific stiffness (E/ρ).
3. Good chemical stability: PEEK has good resistance to acid, alkali, salt, water and gas. Under normal conditions, they do not chemically react with these substances.
4. Good electrical insulation, heat insulation and sound insulation performance.
5. Good wear resistance and self-lubrication: PEEK has a small friction coefficient, good wear resistance, and good self-lubrication. In addition, it has high specific strength and low transmission noise. It can be used in liquid media, semi-dry or even dry friction work effectively under the conditions.
6. Strong bonding ability.
7. Good forming and coloring properties.
