PVDF has good chemical stability, excellent chemical resistance and good heat stability, and can be used for a long time within the range of -62 ℃ -150 ℃. At the same time, the solution constant is large. It is one of good insulating materials. It is resistant to all salts, acids, alkaline halogens and other media except hydrochloric acid and strong solvents. Non-flammable, fatigue-resistant, break-resistant, wear-resistant, good self-lubricating performance, and with its excellent corrosion resistance, unmatched service life, high safety factor, reduced maintenance, will bring you significant comprehensive economic benefits. Products are widely used in chemical, petroleum, chlor-alkali, smelting, pharmaceutical, dye, food, electroplating, environmental protection, pure water and other industrial sectors.
