Application

Ethylene-vinyl acetate copolymer serves a crucial role in various applications due to its impressive properties such as good impact resistance, stress crack resistance, softness, high elasticity, puncture resistance, and chemical stability. This versatile material is primarily used in the production of plastic products, where its compatibility with fillers and flame retardants is highly valued. It is a key component in flexible tubing, color concentrates, gaskets, and molded auto parts, as well as plastic lenses and pumps. Additionally, as an elastomer, it enhances adhesion properties in hot-melt and pressure-sensitive adhesives and is used in conversion coatings and thermoplastics. Beyond these applications, ethylene-vinyl acetate copolymers are integral to the healthcare field, specifically in the creation of laminated transdermal drug delivery systems. They act as efficient membranes and backings, facilitating the controlled release of medications like atenolol, triprolidine, and furosemide, often in conjunction with plasticizers for optimal delivery efficacy. This makes ethylene-vinyl acetate copolymer an invaluable resource in both industrial and medical domains.
