Product Description
PVDF resin for LITHIUM BATTERY
It is a powdery polyvinylidenefluoride homopolymerwith low melt mass flow rate and high molecular weight, soluble in polar organic solvents, with high viscosity and adhesive property.
It can be used as a binder for power batteries, energy storage, digital and other lithium batteries. Its high purity and crystallinityguarantee its long-term and stable tolerance in electrolyte.
