Weather resistance and electrical properties of Teflon plastic raw material spraying powder.

Teflon plastic material spray powder has high chemical resistance, such as concentrated sulfuric acid, nitric acid, hydrochloric acid, even boiled in aqua regia, its weight and properties are unchanged, and almost insoluble in most solvents, only It is slightly soluble in perlane (about 0.1 g/100 g) above 300°C. Not absorbing moisture, incombustible, extremely stable to oxygen and ultraviolet light, so it has excellent weather resistance.
It is worth noting that Teflon spray powder cannot tolerate extremely strong reducing atmosphere, molten alkali metal, ammonia alkali solution (alkali metal dissolved in liquid ammonia), certain fluorides (such as TFA), naphthalene sodium salt, etc. Can quickly corrode Teflon spray powder products.
Electrical properties: Dielectric constant and dielectric loss are low over a wide frequency range, and breakdown voltage, volume resistivity, and arc resistance are all high.
