Dow Engage® ENR 7086.01 Ethylene-Butene Copolymer
Categories:	Polymer; Thermoplastic; Elastomer, TPE; Thermoplastic Elastomer, Melt-Processible Rubber
Material Notes:	ENR 7086.01 is an ethylene-butene copolymer with a broader molecular weight distribution and much higher levels of long chain branching than other commercially available polyolefin elastomers. It is ideally suited for use alone or as an additive to enhance processing in blow molding, extrusion and thermoforming applications where high levels of shear thinning and high melt strength may be required. Information provided by manufacturer.
