1.Chemical resistance:
PTFE has extremely high resistance to chemical corrosion, such as in concentrated sulfuric acid, hydrochloric acid, and nitric acid. Even if it is boiled in aqua regia, its weight and properties are unchanged, and it is almost insoluble in most solvents, only slightly soluble in peralkanes (about 0.1g/100g) above 300 °C.
2.Weather resistance:
PTFE does not absorb moisture, is non-flammable, and is extremely stable to oxygen and ultraviolet rays, so it has excellent weather resistance.
3.Mechanical properties:
PTFE maintains excellent mechanical properties in a wide temperature range of -196 to 260 ° C. One of the characteristics of perfluorocarbon polymers is that it does not become brittle at low temperatures. The density of PTFE is relatively large, which is 2.14-2.20g/cm3, hardly absorbs water, and the equilibrium water absorption rate is less than 0.01%.
PTFE e is a typical soft and weak polymer, the mutual attraction between macro-molecules is small, and the stiffness, hardness and strength are small, and it will deform under long-term stress.
