Product Overview
EVA Granules – Ethylene-Vinyl Acetate Copolymer
EVA (Ethylene-Vinyl Acetate) granules are a high-performance, flexible thermoplastic material created by the copolymerization of ethylene and vinyl acetate. Known for their excellent clarity, flexibility, toughness, and low-temperature performance, EVA granules are widely used in applications ranging from foam sheets and shoe soles to hot melt adhesives, films, and photovoltaic encapsulation.
EVA combines the elasticity of rubber with the processability of thermoplastics, making it a preferred material for a wide range of industries.
