Main advantages:
Resistance to high temperature, the allowable continuous maximum operating temperature is 250 degrees, and up to 310 degrees in short time (Note: the actual mechanical property will drop to half of room temperature at 160 degrees)
High mechanical strength, stiffness and hardness
Excellent chemical resistance and hydrolytic resistance
Excellent wear-resisting and anti-friction properties
High creep strength
Excellent dimensional stability
Excellent resistance to high energy radiation (such as γ-ray and X-ray)
Outstanding anti-ultraviolet property
Excellent resistance to boiling water and high temperature steam
Low flammability, and smoke can be rarely seen when burned
Disadvantages:
 Intolerance to acetone, concentrated sulfuric acid or oxidizer
Such as concentrated nitric acid or aqueous chlorine
Application:
It has been widely used in the aerospace, medical, pharmaceutical and food processing industries: such as gas analyzer on the satellite, structural part and heat exchanging scraper
It has become the ideal material in friction applications for superior friction property
