The basic characteristics of high temperature resistance -- operating temperature up to 250℃.Low temperature resistance -- good mechanical toughness;5% elongation can be maintained even when the temperature drops to -196℃.Corrosion resistance - inert to most chemicals and solvents, strong acid and alkali resistance, water and various organic solvents.Weather resistant - has the best aging life in plastics.High lubrication - lowest friction coefficient among solid materials.
