Product Description of PVDF Resin FR905 Lithium Battery
PVDF Resin FR905 is a powder form of polyvinylidene fluoride, which can be well dissolved by some certain solent.Compared with other grades of PVDF. PVDF Resin 905 is more suitable for electrode binder of lithium battery. PVDF FR905 is a polymeric material with high dielectric constant, which shows high viscosity and bonding property in come certain solvent, and it is easy to form films.Made from virgin PVDF FR905,properly processed electrode of lithium battery shows excellent chemical-stability,high temperature stability,good mechanical properties and processability. PVDF homopolymer is an ultra high viscosity, battery-grade PVDF binder developed specifically for the li-ion battery market. The powder's high purity and crystallinity levels deliver exceptional resistance in electrolytes typically used for lithium-ion battery manufacturing.PVDF binder formulas deliver best-in-class adhesion for lithium-ion battery manufacturers and R&D Laboratories. Our PVDF formulas are available in commercial-scale quantities both as homopolymer and copolymer powders.

Polyvinylidene fluoride (PVDF) resin is a semicrystalline ferroelectric polymer. The formation of polyvinylidene fluoride (PVDF) crystals depends on the processing conditions. Under certain conditions such as stretching, polarization and pouring, these crystalline phases can be transformed to each other. Polyvinylidene fluoride (PVDF) PVDF film is composed of liquid slow cooling or solution casting. The diurnal polymerization of vinylidene fluoride (PVDF), which was formed by stretching and electrochemistry, showed strong piezoelectric and pyroelectric properties.
PVDF, Poly (vinylidene fluoride), polyvinylidene fluoride, unit structure is-CH2-CF2 -. To analyze unit structures, we start with HF or F. Fluorine, halogen elements, in the second cycle, the atomic radius is small, electronegativity is strong, with strong electron absorption, bonding ability is very strong. Assuming that we can disassemble H and F unscientifically and add double carbon to the middle, we can get the unit structure of PVDF-CH2-CF2-whose skeleton C is tetrahedron (as shown below). The electronic cloud of the unit is still skewed to the F end. There are two possible hydrogen bonds, one is the formation of H with other electron-absorbing groups, and the other is the formation of F with other electron donor groups H. This is the chemical property of the PVDF unit structure.
