PVDF is a specialty plastic material in the fluoropolymer family; it is used generally in applications requiring the highest purity, strength, and resistance to solvents, acids, bases and heat and low smoke generation during a fire event. Compared to other fluoropolymers, it has an easier melt process because of its relatively low melting point of around 1770C.
It has a low density (1.78) and low cost compared to the other fluoropolymers. It is available as piping products, sheet, tubing, films, plate and an insulator for premium wire. It can be injected, molded or welded and is commonly used in the chemical, semiconductor, medical and defense industries, as well as in lithium ion batteries
This product have good solubility in some solvent, so, DF-2 PVDF powder is suitable for lithium battery industry as binder.
DF-2 PVDF resin own high dielectric constant, it have higher viscosity and binding properties in some solvent, easy to film. DF-2 PVDF powder as raw materials, the lithium battery membrane have good chemical stability, temperature stability, excellent mechanical strength and workability.
