Carboxyl-Modified Vinyl Chloride/Vinyl Acetate Copolymers VMC

A medium molecular weight resin containing approximately 83 percent vinyl chloride, 16 percent vinyl acetate, and 1 percent maleic acid. Because of the carboxyl functional group, VMC has excellent adhesion on metal, especially on aluminum foil, the resin foil also has a good adhesion on PVC, ABS, paper, textiles, beton, etc. At the same time, VMC has excellent water resistance, oil, ester, acid, alkali and salt water solution resistance.
