Application

Poly(ethylene-co-vinyl acetate), containing 18 wt. % vinyl acetate and with a melt index of 8 g/10 min at 190°C/2.16kg, is a versatile elastomer primarily used to enhance the adhesion properties in hot-melt and pressure-sensitive adhesives, as well as in conversion coatings and thermoplastics. This material is known for its excellent impact and stress crack resistance, softness, high elasticity, and puncture resistance, alongside its chemical stability and good electrical properties. It also exhibits good biocompatibility and low density, making it compatible with various fillers and flame retardant agents. Among its applications, it is particularly useful in making flexible tubing, color concentrates, gaskets, molded automotive parts, plastic lenses, and pumps. Moreover, ethylene-vinyl acetate copolymers are widely used in medical applications such as membranes and backings in laminated transdermal drug delivery systems. They provide an effective matrix and membrane for the controlled release of medications like atenolol, triprolidine, and furosemide, offering potential for further development in drug delivery systems with the addition of plasticizers.
