Jiangsu Junhua Special Plastics Technical Data: PEEK has excellent high and low temperature resistance

1. The meaning, measurement method and measurement results of several heat resistance performance indicators of PEEK: glass transition temperature, melting point, heat deformation temperature, continuous use temperature, thermal expansion coefficient, thermal conductivity.

2. Note: The thermal conductivity of PEEK composite materials containing glass fiber and carbon fiber is higher than that of pure PEEK, but the thermal expansion coefficient becomes smaller.

3. Comparison of heat deformation temperature of PEEK and other high-performance materials

4. Comparison of long-term use temperature of PEEK and other high-performance materials PEEK and its composite materials have excellent heat aging resistance. Whether it is pure PEEK or glass fiber or carbon fiber reinforced PEEK, the tensile strength will not decrease significantly after 1000 hours of heat aging. The service life of PEEK-coated cables at 220°C is more than 6000 hours.
