Polyvinylidene Fluoride (PVDF), known as the "all-rounder" in the fluoroplastic family, combines the excellent stability of fluororesins with the processability of general-purpose plastics, reshaping multiple industries with its unique advantages. This semi-crystalline fluoropolymer has a fluorine atom content of 59% in its molecular chain and a carbon-fluorine bond energy of 485 kJ/mol, endowing it with a wide service temperature range of -40β to 150β and outstanding weather resistance.
PVDF's development is a remarkable cross-border success story. Accidentally discovered in 1946, it achieved industrial production in 1960 and was initially used in chemical corrosion protection. In recent years, the explosive demand from the new energy industry has become the core driver, with lithium battery-grade PVDF accounting for 38% of the market, making it the largest application area. Although China's industry started late, it has developed rapidly. In 2024, China's PVDF production capacity reached approximately 224,000 tons, accounting for a major global share, concentrated in Shandong, Zhejiang, and Jiangsu provinces.
Today, PVDF is widely used in lithium batteries, high-end architectural coatings, chemical corrosion protection, electronics and electrical engineering. In the future, it will move towards high-endization to adapt to high-nickel batteries while exploring emerging application scenarios such as hydrogen energy and semiconductors, continuously demonstrating the diverse value of this "plastic special forces".
