| D-1 PVDF Lithium Ion Battery Binders |
|
D-1 PVDF are widely used as binders in lithium ion battery industry, and as battery separators in lithium-ion polymer technology.
D-1 PVDF is high dielectric constant, which shows high viscosity and bonding properties in some solvent, easy to form film. D-1 PVDF powder as raw materils, the lithium ion battery membrane have good chemical stability, temperature stability, excellent mechanical strength and processability.

Safety instruction
D-1 PVDF is stable under 310deg.C, when it is stored at 310-320deg.C for a long time, trace toxic hydrogen fluoride(HF) and fluorocarbon organic chemicals(FC) begin to release, when the temperatures more than 370deg.C, HF and FC release speed up. So, a temperature below 310deg.C is suggested for processing and using D-1 PVDF.
Furthermore, although D-1 pvdf have good flame retardancy, in case of fire, HF and FC will also be released.
