Product Description

Product Description

Zheflon^® FL2600 PVDF- Lithium Battery Binders
Grade

Zheflon®FL2600 is a polyvinylidene fluoride copolymer with a medium to high viscosity grade. The molecule contains special functional groups, which can reduce the crystallinity of the polymer while giving the material a certain degree of flexibility. It can strengthen the polymer molecules, active materials and metal pole pieces. It can improve the adhesion performance and is especially suitable for the application of lithium cobalt oxide and lithium iron phosphate systems in the electric vehicle industry.
Zheflon®FL2600 can effectively reduce the amount of formula used, reduce the DC internal resistance of the battery, improve the energy density and charge and discharge performance of the battery, and effectively increase the capacity retention rate of the battery during the cycle, thereby meeting the needs of the automotive industry.

Packing & Storage

• Process safety instructions

1. This product should be processed under 260ºC to avoid producing toxic gases.
2. PVDF has good fire resistance and smoke inhibition property. While, it will release toxic gas and fluorocarbon. compounds when meets with fire.
3. Operators should pay attention to personal protection during the processing and operating.

• Packaging and storage

PVDF is packed in a plastic bag and then be put into a PE bag with the net weight 25KGS. It must be stored in clean, cool, dry place.
