Polyvinyl Chloride Acetate (PVCA)

Properties and Applications

Polyvinyl chloride acetate (PVCA) is a transparent, mostly amorphous thermoplastic copolymer of about 80-95% vinyl chloride and 5-20% vinyl acetate. PVAC resins have high transparency, are odor- and tasteless, and are very tough, and durable. These resins also possess outstanding heat seal qualities and are compatible with many resins, plasticizers and solvents.

PVCA can be used either as a base resin or as an additive to other polymers (PVC) and formulated products. The resins are available in both powders and solutions. They are sometimes added to coatings, adhesives, inks, and paints due to their excellent processing and flow properties as well as high flexibility and transparency. Major applications include heat seal adhesives for aluminum foils, metal coating adhesives, floor coatings (wood paints), gravure inks, PVC plastisols, and molded products of high durability such as credit cards.
