Description
Styrene-Butadiene Rubber (SBR) Binder for Li-ion Battery Anode Materials
Our Styrene-Butadiene Rubber (SBR) Binder is a high-quality water-based emulsion specifically designed for lithium-ion battery anode materials. With its milky-white appearance, excellent film-forming ability, strong adhesion, and aging resistance, it is ideal for the formulation of anode slurries and can also be used in select cathode systems. Its water solubility supports eco-friendly processing and easy cleanup.
