Description

Poly(Vinyl Chloride-Co-Vinyl Acetate) is a versatile copolymer that combines the rigidity and chemical resistance of PVC with the flexibility and processability imparted by vinyl acetate. This material is engineered to offer superior performance in applications requiring enhanced impact strength, clarity, and adhesion properties compared to standard PVC. It is a critical raw material for manufacturers in the adhesives, coatings, films, and specialty plastics industries seeking to improve product durability and functionality.

Application

• Adhesive Formulations: Used as a key resin in solvent-based and hot-melt adhesives, providing excellent tack and bond strength for labels, tapes, and laminates.
• Surface Coatings & Inks: Serves as a film-forming agent in industrial and decorative coatings, printing inks, and varnishes, offering good gloss and substrate adhesion.
• Flexible Films & Sheets: Employed in the production of clear, flexible packaging films, calendered sheets, and synthetic leather where improved low-temperature flexibility is required.
• Molding Compounds: Used in injection molding and extrusion for producing parts with good dimensional stability and impact resistance.
• Sound Damping Materials: Incorporated into underbody coatings and sealants for automotive and construction applications due to its vibration damping characteristics.
• Textile & Fiber Treatment: Applied as a binder or coating to impart stiffness, water resistance, or flame retardancy to fabrics and non-wovens.
