Insulation: It is not affected by the environment and frequency. The volume resistance can reach 1018 ohm·cm, the dielectric loss is small, and the breakdown voltage is high.
High and low temperature resistance: The effect on temperature is not changed much, and the temperature range is wide. The temperature can be used between -190 and 260 °C.
Self-lubricating: It has the lowest coefficient of friction in plastic and is an ideal oil-free lubricant.
Non-adhesive surface: A known solid material does not adhere to a surface and is the solid material with the lowest surface energy.
Resistance to atmospheric aging, radiation and low permeability: long-term exposure to the atmosphere, surface and performance remain unchanged.
Chemical resistance and weather resistance In addition to molten alkali metal, PTFE is hardly corroded by any chemical agents. For example, in concentrated sulfuric acid, nitric acid, hydrochloric acid, or even in aqua regia, there is no change in weight and properties, almost insoluble in all solvents, and slightly soluble in perparaffins (about 0.1) g / 100 g) only above 300 °C. Teflon does not absorb moisture, is non-combustible, is extremely stable to oxygen and ultraviolet rays, and therefore has excellent weather resistance.
