EVA Hot Melt Adhesive Product Introduction

EVA is a plastic material composed of ethylene (E) and vinyl acetate (VA). The ratio of these two chemicals can be adjusted to meet different application requirements. A higher VA content increases transparency, softness, and toughness. Ethylene/Vinyl Acetate Copolymer (EVA)
Ethylene-vinyl acetate copolymer (also known as ethylene-vinyl acetate copolymer) is produced by the copolymerization of ethylene (E) and vinyl acetate (VA). Its English name is Ethylene Viny Acetate, abbreviated as EVA, or E/VAC. Polymerization methods include high-pressure bulk polymerization (for plastics), solution polymerization (for PVC processing aids), emulsion polymerization (for adhesives), and suspension polymerization. EVA with a vinyl acetate (VA) content above 30% is polymerized by emulsion polymerization, while those with a lower VA content are polymerized by high-pressure bulk polymerization. EVA has a wide range of applications. Generally speaking, EVA with a vinyl acetate content below 5% is primarily used in films, LDPE modifiers for wire and cable, and adhesives. EVA with a vinyl acetate content of 5%-10% is used in elastic films. EVA with a vinyl acetate content of 20%-28% is primarily used in hot-melt adhesives and coatings. EVA with a vinyl acetate content of 5%-45% is primarily used in films (including agricultural films) and sheets, injection molding, molded products, foam products, and hot-melt adhesives. It is widely used in foamed shoe materials, functional greenhouse films, packaging molds, hot-melt adhesives, wire and cable, and toys.
