Polytetrafluoroethylene is easy to be internally cooled and stress relaxation under the bearing capacity and high temperature weather, so it is generally used for low pressure, normal pressure, strong corrosion and chemical substances that cannot pollute the environment, such as strong acid, strong alkali, halogen bulb, drugs, etc. The operating temperature of safety factor is 150 ℃, and the pressure is below 1MPa. Although the tensile strength of filled PTFE is higher, the application temperature is not more than 200 ℃
