| Polytetrafluoroethylene tube |
| Characteristics：Polytetrafluoroethylene bar has 2 types. The polytetrafluoroethylene bar with the diameter of 1-9 mm is made |
by polytetrafluoroethylene resin, that with the diameter of 10-50mm is made by suspending polyfluortetraethylene resin and |
| that of over 50mmis manufactured by molding. It has the best chemical corrosion proof and dielectric property with the |
| characteristics of age proof and non-adhesive. It can be used in the temperature range of -180%°C - +260°C (no loading). It |
| also has the lowest friction coefficient in the known solid material. |
