sorry,there are no info now!

1. PTFE mixture can protect the shaft, while machine is running in operation.

2. It is with low friction coeffcient, a good anti-wear.

3. Good running-in property.

4. It fits well in motion of rotation, swinging and reciprocation.

5. Good anti-corrosion.

6. It can be used in food machines, pharmaceutical equipments etc, due to lead-free.

7. Typically, it is mainly used in the conditions of acid and alkali, such as chemical industry  (such as pumps, valves etc.) and printing & dyeing machinery, marine industry.
