Vt475 is a VDF copolymer. It is used as an additive of PVDF, which improves the water absorption of high nickel NCM / NCA positive electrode and 4.48v/4.5v LCO positive electrode pastes, suppresses the gel trend of the pastes, improves the flexibility of the pole pieces, suppresses the breakage of the pole pieces, improves the compaction and long cycle performance.
Usage Suggestions：Mixed with high molecular weight PVDF, VT475: PVDF=20~30:70~80
