Poly(vinylidene fluoride), or PVDF, is a semi-crystalline thermoplastic fluoropolymer known for its high chemical resistance, excellent mechanical properties, and strong piezoelectric characteristics. It is widely used in chemical processing equipment, membrane filtration systems, and electrical/electronic applications where resistance to corrosive fluids and high-temperature stability are critical; engineers select PVDF over other polymers when durability in harsh chemical environments and long service life justify the material cost.
