Product Overview
Description
Product Description
PVDF(Polyvinylidene fluoride)
PVDF is a highly non-reactive thermoplastic fluoropolymer produced by the polymerization of vinylidene difluoride. Its chemical formula is (C2H2F2)n.
PVDF is a specialty plastic used in applications requiring the highest purity, as well as resistance to solvents, acids and hydrocarbons. PVDF has low density 1.78 g/cm3 in comparison to other fluoropolymers, like polytetrafluoroethylene.

Specification
Product Technical Property of PVDF FR9205
FR9205-PVDF powder, it is a resin is a lithium battery grade with super high molecular weight produced in the way of suspension polymerization. The molecules contain polar functional groups, which can improve the adhesion between active substances, metal plates and polymers, and effectively reduce the use of the formula. This grade is mainly used in power batteries with high capacity, high rate and high cycle.
