Lotte EVA Resins

Lotte EVA resins are a range of ethylene-vinyl acetate copolymers developed and manufactured by LOTTE Chemical. Produced through high-pressure polymerization technology, these materials are engineered to provide a balanced combination of flexibility, elasticity, processability, adhesion, and heat-sealing performance.

By varying vinyl acetate (VA) content and melt flow characteristics, the EVA portfolio can be tailored to meet diverse processing requirements and end-use needs. The product series are widely used in hot-melt adhesives, footwear components, foam products, flexible packaging, films, wire and cable compounds, and a variety of specialty plastic applications.
