Product Description

1.Product Introduction

DY-10 is a high viscosity polyvinylidene fluoride resin prepared by suspension method and modified by copolymerization.
The polar functional groups in the comonomer can improve the bonding properties between the active substance, the metal electrode sheet and the polymer, and effectively reduce the formula usage.
The product can be used for high capacity, high rate, high cycle power battery production.
