What is the chemical properties of raw meal belt


Insulation: 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: it has little effect on temperature, wide temperature range, and can be used at - 190 ~ 260 ℃.


Self lubricity: with the smallest friction coefficient in plastics, it is an ideal oil-free lubricating material.


Surface is not sticky: known solid materials can not adhere to the surface, is a surface energy of the smallest solid materials.


Atmospheric aging resistance, radiation resistance and low permeability: long term exposure to the atmosphere, the surface and performance remain unchanged.


Corrosion resistance


Chemical resistance and weather resistance except for molten alkali metal, polytetrafluoroethylene is hardly corroded by any chemical agent. For example, when it is boiled in concentrated sulfuric acid, nitric acid, hydrochloric acid or even aqua regia, its weight and performance have no change, and it is almost insoluble in all solvents, only slightly soluble in paraffins (about 0.1g/100g) above 300 ℃. Polytetrafluoroethylene is non hygroscopic, non combustible, extremely stable to oxygen and ultraviolet, so it has excellent weather resistance.
