Polyvinylidene fluoride (PVDF), also known as polyvinylidene difluoride, is a semi-crystalline thermoplastic that belongs to the fluorine polymers group. PVDF is widely used in the form of membranes, coatings, pipes, sheets, and films in various end-use industries such as electrical and electronics, oil and gas, PV modules, automotive, chemical processing, building and construction, textiles, wires and cables, water treatment, etc. Polyvinylidene fluoride offers high corrosion resistance, weatherability, good adhesion, high thermal stability, and good chemical resistance. Cast parts, membranes, monofilament and drawn fibers, tubing, sheets, and rods are produced from polyvinylidene fluoride.
PVDF is a high-grade thermoplastic polymer produced by the chemical transformation of vinyl chloride into vinyl chloride terephthalate. Thermoplastic polymers are especially valuable in applications that require the use of high temperatures, since polyvinylidene fluoride contains the ability to resist extreme temperatures. PVDF also has excellent thermal conductivity, which makes it an ideal material for thermal insulation.
Polyvinylidene fluoride is widely used as insulation on wires due to its high heat resistance, high chemical resistance, low weight, and low thermal conductivity. Moreover, PVDF tubes, pipes, and hoses are used in the automobile fuel systems due to its properties such as chemical resistivity and impermeable nature. With the increasing use of polyvinylidene fluoride from various end-use industries, such as automotive, the demand for polyvinylidene fluoride is also increasing. Automakers sold more than 17 million vehicles in the U.S. for a fifth consecutive year in 2019.
PVDF is widely used in various chemical processing industries as metallic coatings for various applications such as pumps, membrane, filters, and heat exchangers. Polyvinylidene fluoride offers superior abrasion/chemical-resistance, corrosion barrier, thermal resistance, and high performance in harsh. Moreover, with the increasing use of polyvinylidene fluoride in the building and construction industry due to its characteristics, such as anti-skid, UV resistance, thermal resistance, wear resistance, chemical resistance, and abrasion resistance, the demand for PVDF is also increasing.
