Semicrystalline polymer. Material has high mechanical and thermal properties (up to 240°C). It resists creep under load, has good wear properties and a low friction coefficient. Temperature resistance is considerably reduced if material is under load.

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 to 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
