Ethylene vinyl acetate copolymers (EVA) are thermoplastic polymers comprised of repeated units of ethylene and vinyl acetate. A more elastomeric product than polyethylene.
It stands out for its excellent processability, flexibility and compatibility. The presence of polar groups in its structure improves its performance significantly in terms of cohesion and adhesion to different substrates. The higher the vinyl acetate content, the higher the adhesion.
Under its new Primeva® brand, Repsol produces and markets EVA copolymers designed for well-known applications like hot melt adhesives, films and microcellular foams.
