DuPont Elvaloy® 3108 AC Ethylene and 7% Butyl Acrylate Copolymer (discontinued **)
Categories:	Polymer; Film; Thermoplastic; Ethylene Butyl Acrylate
Material Notes:	Elvaloy® 3108 AC contains antioxidant, slip and antiblock additives. Elvaloy® 3108 AC is developed to give films with good sealing properties, impact strength at lower temperature, and low shrinkage temperature. Processing characteristics of Elvaloy® 3108 AC are similar to LDPE and conventional polyethylene extruders are recommended. Information provided by DuPont. This product line/trade name was acquired by Dow, but this specific grade was discontinued prior to the acquisition.
