What is PVDF material

PVDF

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.

Magnetic Pump Series

PVDF magnetic pump is a new type of chemical pump, it is made of PVDF material, which has excellent properties such as corrosion resistance, high temperature resistance and wear resistance. It also adopts magnetic drive technology, which eliminates the need for mechanical seals and avoids the problems of leakage and pollution, making it a very environmentally friendly and safe pump.

PVDF centrifugal pump is a chemical pump with high performance and applicability, made of PVDF material, with excellent corrosion resistance. It is suitable for conveying corrosive, flammable and explosive, toxic and harmful special media.

PVDF vertical pump is a new type of chemical pump, which is made of PVDF material and has excellent properties such as corrosion resistance, high temperature resistance and wear resistance. It also adopts a vertical structure design, which can effectively save space and improve the efficiency and stability of the pump.

Precision chemical filters are a type of filtration equipment used in chemical production to ensure the purity of chemical solutions in the production process and are particularly suitable for production processes requiring high purity and precision.

In addition to the above applications, it is worth noting that QEEHUA PUMP’s chemical pumps are made from high-quality PVDF or ETFE corrosion-resistant materials. These pumps are used to transfer or circulate corrosive chemical fluids and are crucial industrial fluid equipment.
