1. PTFE/Pb composition, 0.01-0.03mm, anti-abrasion material, which will form
a lubricating film during operation.
2. Bronze powder layer, 0.2-0.35mm, which further strengthen the combination of the bronze plate and PTFE layer and transfer the heat more quickly.
3. Bronze plate, bear high load and transfer heat, anti-corrosion.

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