1. High mechanical strength and rigidity; 2. Highest fatigue strength; 3. Good environmental resistance and organic solvent resistance;
4, strong resistance to repeated impact; 5, a wide range of use temperature (-40 ℃ ~ 120 ℃); 6, good electrical properties;
7. Good resilience; 8. Self-lubricating and abrasion resistance; 9. Excellent dimensional stability.
Strong acid corrosion, poor weather resistance, poor adhesion, thermal decomposition and softening temperature are close, the oxygen limit index is small.
