1. Non sticky: almost all substances do not adhere to the PTFE coating. Very thin films also show good non adhesion properties.
2. Heat resistance: polytetrafluoroethylene coating has excellent heat resistance and low temperature resistance. It can withstand high temperature to 280 ℃ for a short time and can be used continuously at 250 ℃ with remarkable thermal stability. It can work at freezing temperature without embrittlement and melting at high temperature.
3. Sliding property: polytetrafluoroethylene coating has low friction coefficient. The friction coefficient changes when the load slides, but the value is only between 0.05 and 0.15.
4. Moisture resistance: the surface of polytetrafluoroethylene coating is free of water and oil, and it is not easy to touch the solution during production and operation. If there is a small amount of dirt, it can be removed by simply wiping. Short downtime, saving man hours and improving work efficiency.
5. Wear resistance: it has excellent wear resistance under high load. Under a certain load, it has the double advantages of wear resistance and non adhesion.
6. Corrosion resistance: polytetrafluoroethylene is widely used in industries requiring high temperature resistance and high viscosity. Among them, the stronger acid -- fluoroantimonic acid can also be used for preservation.
