Product Description

polyvinylidene fluoride modified copolymer with medium and high viscosity grades. The molecule contains polar functional groups, which can enhance the work force between polymer molecules, active materials and metal pole pieces, and improve adhesion performance and Corrosion resistance in electrolyte. Especially suitable for the application of the ternary material system in the electric vehicle industry.
Zheflon^®FL2100 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.

• 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. However, it releases toxic xxxxx 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 PE plastic bag and then packed in cardboard box with the net weight 25KGS. It must be stored in clean, cool, dry place.
