Polyetheretherketone (PEEK)
PEEK has excellent mechanical strength, dimensional stability, a low coefficient of friction, very good chemical, hydrolysis resistance and radiation resistance, good dielectric properties. Low notch impact strength. UL94 Vo rated (self extinguishing). Temperature range -50°C to +250°C.
FEATURES
 High temperature; resists beyond 240°C. (The Heat
distortion temperature is 162°C)
Dimensional stability
Good chemical resistance
Good abrasion resistance and low friction coefficient.
Excellent electrical properties.
WEAK POINT
Very high cost.
Load bearing decreases above 140° C.
Not inherently U.V. stable.
APPLICATION
Mechanical: The dimensional stability at temperature is high, as well as the heat resistance. The components obtained have a high wear resistance and are self-lubricated. It is used for high performance pieces at low as well as at high temperatures:gears bushes, in aircraft and aerospace
industries.
Nuclear: High resistance to gamma radiation
Electrical: Very good dielectric and insulating properties.
Chemical: Very good chemical resistance. Ball valve seals, pump housings
Heat distortion point at 1,8 N/mm2 |
