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
sealing washer for piston, sealing ring; sliding bearing
bearing sleeve; valve seat, thimble, connecting plug
