AF825 Low Temp PAEK Properties
Cryogenic PEEK AF825 offers higher tensile strength with a lower modulus compared to PCTFE, which means that it is better suited for use in applications that require strength and durability while still maintaining flexibility. Furthermore, the material has a lower coefficient of thermal expansion than PCTFE, which makes it highly resistant to dimensional changes that can occur due to temperature fluctuations.
Higher tensile strength
Lower and constant coefficient of thermal expansion
Higher thermal conductivity
Lower static and dynamic coefficient of friction
More expensive due to complex manufacturing process
Susceptible to UV degradation
Limited chemical resistance
