What is PVDF material


Polyvinylidene fluoride (PVDF) is a highly popular fluoropolymer that has gained significant popularity in recent years due to its excellent processing properties. It is the second most widely used product in the fluoroplastics family, after polytetrafluoroethylene (PTFE).

PVDF is extensively used in applications where high purity and resistance to solvents and acids are crucial. Although its tensile modulus is similar to that of ethylene tetrafluoroethylene (ETFE) and ethylene chlorotrifluoroethylene (ECTFE), it has a lower impact strength. Moreover, PVDF is chemically inert, unlike partially fluorinated polymers such as chlorotrifluoroethylene (CTFE) and ECTFE. PVDF dissolves in organic solvents, such as esters and amines, at high temperatures, which makes it suitable for use as a corrosion-resistant coating for chemical processing equipment and building panels.

PVDF is highly resistant to mineral and organic acids, aliphatic and aromatic hydrocarbons, alcohols and halogenated solvents. It also has excellent gas barrier properties, piezoelectricity, and thermoelectricity.

The exceptional chemical resistance, processability, fatigue resistance, and creep resistance of PVDF make it an ideal material for lining or integral parts of pumps and valves in fluid handling systems for petrochemical equipment. It is also commonly used in pipes, fittings, storage tanks, and heat exchangers. Additionally, its good chemical stability and electrical insulation properties enable the production of equipment that meets Total Organic Carbon (TOC) and flame-retardant requirements. PVDF is widely used in the semiconductor industry for storing and transporting high purity chemicals.

PVDF has recently been used in the manufacture of porous membranes and coagulants. It is also used as a binder in lithium secondary batteries and diaphragms, making it one of the fastest-growing markets for PVDF demand.
