Product Details

Product Name:VP/VA Copolymers

Chemical Description:Vinylpyrrolidone with Vinyl Acetate Copolymer

INCI/CTFA:VP/VA Copolymer

CAS NO.:25086-89-9

Formula structure:

Product Properties:VP/VA Copolymers with different rations of N-Vinylpyrrolidone to Vinyl Acetate,soluble in most organic solvents.Which exists in powder,water solution and ethnol solution form.VP/VA compolymer forms hard,water-removable and glossy films,it has excellent compatibility with many plasticizers and modifiers,and the hydroscopicity decreases in proportion to the ration of Vinyl acetate.
