Wacker Vinnapas® 323 Vinyl Acetate-Ethylene Copolymer
Categories: Polymer; Thermoplastic; Ethylene Vinyl Acetate

Material Notes: Product description: VINNAPAS® 323 is a poly(vinyl alcohol) stabilized vinyl acetate-ethylene copolymer dispersion with a glass transition temperature (Tg) of +23 °C. It was developed as a fast setting, high heat resistant dispersion with fully hydrolyzed PVOH compatibility.

Properties: VINNAPAS® 323 is designed for use as a base for high-speed packaging applications. It exhibits excellent wet tack, speed of set and medium plasticizer thickening response. Because of its poly(vinyl alcohol) stabilization and excellent mechanical stability, this dispersion can be used in a variety of roll, extruder, or spray applications. The dry film is tack free and heat sealable. This dispersion is compatible with both fully and partially hydrolyzed alcohol. The very good water resistance can be enhanced when the dispersion is compounded with fully hydrolyzed alcohol. Having the highest Tg, this dispersion exhibits the highest heat resistance, high tensile strength, and moderate flexibility.

Application: VINNAPAS® 323 is a versatile base for adhesive formulators with the rheology that makes it suitable for use in a variety of high speed packaging applicationssuch as corrugated case sealing. With good water resistance, it is suited for but not limited to applications such as bag seams, corrugated case forming and sealing, carton forming, and cup forming. Strong wet tack allows this dispersion to be used in collating. The combination of heat resistance and water resistance makes VINNAPAS® 323 a solid ingredient in adhesive formulations designed for laminations of porous substrates, e.g., paper or board to wood products.
