EVA High VA Hotmelt — Ethylene Vinyl Acetate (High VA) for Hot Melt Adhesives
High vinyl acetate content EVA (above 28% VA) is primarily used as a component in hot melt adhesives, offering excellent tack, flexibility, and adhesion to a wide range of substrates. It provides a good balance of properties for bonding in packaging, bookbinding, and woodworking.
