Dow Elvaloy® 1820 AC Ethylene and 20% Methyl Acrylate Copolymer
Categories:	Polymer; Film; Thermoplastic; Ethylene Methyl Acrylate; Ethylene-Methyl Acrylate Copolymer, Molding Grade
Material Notes:	Elvaloy® 1820 AC is intended for film coextrusion, compounding and injection molding. Due to its high melt flow rate, it also can be used in extrusion coating/lamination. Elvaloy® 1820 AC has good adhesion to carious substrates (OPA, OPP, paperboard, etc.), gives excellent sealing properties and has high filler acceptance. Elvaloy® 1820 AC is easily processed on standard equipment used for low density polyethylene. Information provided by DuPont. This former DuPont product line is now a Dow product line.
