Carboxyl-Functional Vinyl Chloride/Vinyl Acetate/Maleic Acid Terpolymer
ANHUI LIWEI CHEMICAL CO.,LIMITED
[Introduction]
Vinyl chloride, vinyl acetate, and maleic acid terpolymers are versatile materials renowned for their unique properties. The carboxylated derivatives (containing -COOH groups) enhance adhesion and compatibility with other substances. These terpolymers, derived from polymerization processes, are widely used across various industries. In adhesives, they provide strong adhesion and good flexibility. As coatings, they offer chemical resistance and weather resistance. In printing inks, they contribute to good pigment dispersion and film formation. Furthermore, these terpolymers are also used as sealants and modifiers, demonstrating their adaptability and effectiveness in formulations of various commercial products.
