PEEK high and low temperature resistance characteristics

PEEK has excellent resistance to high and low temperatures

1. The meaning, measurement method, and measurement results of several heat-resistant performance indicators of PEEK: glass transition temperature, melting point, thermal deformation temperature, continuous use temperature, thermal expansion coefficient, and thermal conductivity coefficient.
2. Note: PEEK composite materials containing glass and carbon fibers have an increase in thermal conductivity compared to pure PEEK, but a decrease in thermal expansion coefficient.

5. PEEK and its composite materials have excellent heat aging properties. Whether it is pure PEEK or glass fiber or carbon fiber reinforced PEEK, after 1000 hours of heat aging, the tensile strength will not significantly decrease. The service life of PEEK coated cables is over 6000 hours at 220 ℃.
