Product Introduction
Ethylene-Vinyl Acetate Copolymer (EVA, CAS 24937-78-8) is a thermoplastic polymer formed by the copolymerization of ethylene and vinyl acetate. It combines the flexibility of polyethylene with the polarity of vinyl acetate, offering excellent transparency, toughness, low-temperature resistance, and good adhesion.
EVA is widely used in footwear, packaging films, wire and cable, hot-melt adhesives, photovoltaic films, toys, daily necessities, and foam materials, making it a key polymer material across many industries.
