Application

1. PTFE with oil fibre can protect the shaft, while machine operated.
2. It is of low friction coefficient, good anti-wear. 
3. Good running in property. 
4. It fits well in motion of circumrotation, sway and to-and-fro. 
5. Good anti-corrosion. 
6. It can be used in food machine, pharmaceutical machine etc. due to lead-free. 
7. It is mainly used in the condition of medium acid and alkali, such as chemical industry, pumps, valves etc.
