Antichemical PTFE Bearing (Applicable to the hydrofluoric acid environment)
PTFE can work continuously at -40 °C –200 °C and has the best chemical resistance among engineering plastics.
It has resistance to all types of chemicals, low friction factor, good electric insulation, and is not sensitive to temperature.

- Advantages
-
It is stable at a high temperature and can work continuously at -40 °C –200 °C .
The surface friction factor is low (0.05–0.1) with good electric insulation.
It has a long service life, good wear resistance, and adhesion.
It has a low water absorption rate.
It is resistant to different types of acid, as well as alkali and other types of chemical liquid.
- Disadvantages
-
It is susceptible to deformation and has low strength.
It is hard to mold, inject, and press.
Its dimensional stability is not good.
