Solef Battery Grade 5130 Polyvinylidene Fluoride (PVDF) Powder Binder

Model:

SOLEF-PVDF5130

Material Name:

Polyvinylidene Fluoride (PVDF)

Application:

Battery Binder

Overview:

PVDF5130 is produced by suspension polymerization and has a molecular weight of 1.1 million. It features a relatively large particle size of approximately 100 microns. With the introduction of polar functional groups, it offers higher purity, enhanced viscosity, and superior adhesion performance, allowing for reduced usage. PVDF5130 is particularly suitable for lithium-ion battery applications because of its ultra-high viscosity
