Physical and chemical properties
Polyvinylidene fluoride is a semi-crystalline linear polymer, a fluorine-containing polymer formed by the homopolymerization of vinylidene fluoride monomer. Due to the high structural regularity of the PVDF molecular chain and the relatively small radius of the fluorine atom, the carbon-carbon single bond can diversify the geometrical arrangement of the fluorine and hydrogen atoms in space through internal rotation, that is, the molecular segments show different Conformation, resulting in PVDF has more crystal phases, so far reported five crystal forms α, β, γ, δ and ε, but the report on the ε phase is still very few. At present, the industrial polymerization methods are mainly suspension polymerization and emulsion polymerization.
Because PVDF has good mechanical strength, chemical stability, electrochemical stability, thermal stability and good affinity for electrolytes, it is mainly used in lithium batteries, photovoltaics, coatings, injection molding, water treatment films and other fields. The second largest product in the production of fluorine-containing plastics.

Applications
PVDF has good chemical resistance, processability, fatigue resistance and creep resistance, and is one of the best materials for pumps, valves, pipes, pipe fittings, storage tanks and heat exchangers in the whole or lining of petrochemical equipment fluid handling systems. one.
PVDF is one of the most important raw materials for fluorocarbon coatings. The fluorocarbon coatings prepared from it have developed into the sixth generation. Because PVDF resin has super weather resistance, it can be used outdoors for a long time without maintenance. It is widely used in power stations, airports, highways, high-rise buildings, etc.
PVDF resin can also be modified by blending with other resins. For example, PVDF and ABS resin are blended to obtain composite materials, which have been widely used in construction, automobile decoration, and home appliance shells.
