Polyvinylidene fluoride

Polyvinylidene fluoride (CAS 24937-79-9), commonly known as PVDF, is a high-performance fluoropolymer resin used where chemical resistance and thermal stability are sourcing criteria.

Where is Polyvinylidene fluoride used?

• Electronics and batteries: primary binder for lithium-ion battery electrode coatings
• Chemical processing: piping, pumps, valves and tank linings resistant to acids, solvents and halogens
• Architectural coatings and facades: weathering resistance and colour retention
• Water treatment and pharmaceutical filtration: base polymer cast into microporous structures
• It functions as a structural and functional material where conventional polymers fail.
• In Europe, used in automotive fuel lines, with PA11 on the outer layer and it on the inner layer.
• Film form used to encapsulate photovoltaic cells and protect them from moisture.
• Processed by injection molding, extrusion and welding.

Good to know: Standard grades include homopolymer and copolymer variants, with battery-grade and membrane-grade specifications. Purity and molecular weight vary by end-use, with binder grades under tight quality controls.

Formulation notes

• Not recommended for contact with sodium hydroxide at concentrations above 10% and temperatures above 60°C.
• Can be processed by conventional melt methods, whereas PTFE requires specialized techniques.
• Not recommended for use with dimethylformamide (DMF) above approximately 60°C.
• Not recommended for use with ketones, esters, amines, and some organic acids.

Typical specification

• Typical continuous service temperature approximately 150°C, depending on grade.

Regulatory status

• Achieves UL 94 classification V-0 at a thickness of 3.0 mm.

Storage, packaging and handling

• UL94 flammability rating of V-0 to 5VA.
