VP/VA Copolymer
Product Description:
VP/VA Copolymers produce transparent, flexible, oxygen permeable films which adhere to glass, plastics and metals. Vinylpyrrolidone/Vinyl acetate (VP/VA) resins are linear, random copolymers produced by the free-radical polymerization of the monomers in diferrent ratios.VP/VA Copolymers are available as white powders or clear solutions in ethanol and water. VP/VA copolymers are widely used as film formers because of their film flexibility, good adhesion, luster, water remoistenability and hardness. These properties make PVP/VA copolymers suitable for a variety of industrial, personal care and pharmaceutical products.
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 Copolymers' aqueous solutions are non-ionic, neutralization not required, Resultant films are hard, glossy, and water-removable; Tunable viscosity, softening point and water sensitivity depending on VP/VA ratio; Good compatibility with many modifiers, plasticizers, spray propellants and other cosmetic ingredients,and the hydroscopicity decreases in proportion to the ration of Vinyl acetate.
