Model:
SOLEF-PVDF5130
Material Name:
Polyvinylidene Fluoride (PVDF)
Standard Package:
80g/bottle, 300g/bottle
Application:
Battery binder
Overview:
PVDF5130 is produced by suspension polymerization, with a molecular weight of 1.1 million. The particle size of 5130 is relatively large, about 100 microns. It contains polar functional groups, resulting in higher purity, improved viscosity, and better adhesion properties, allowing for reduced usage.
Due to its ultra-high viscosity, PVDF 5130 is especially suitable for lithium-ion batteries.
