Description

The most thermally stable of all high-pressure PE copolymers, ethyl methyl acrylate (EMA) copolymers can be processed by extrusion coating lamination, blown/cast monolayer and coextruded films, injection molding, sheet or profile extrusion, blow molding and foam extrusion. It produces soft, elastic film (under 1.0 mil thick) with good handling characteristics and without the need for additives and increases impact strength or lowers the modulus in alloys, blends or compounds
