Dow's latest polyolefin elastomer aimed at auto sector

Horgen, Switzerland - The Dow Chemical Company has introduced ENR 7487.00 developmental polyolefin elastomer (POE), the latest in its family of high-melt-strength (HMS) POEs. The new grade is aimed at processes such as extrusion blow molding, thermoforming and high-shear profile extrusion.

“Dow's next-generation high-melt-strength POEs help deliver a combination of low-temperature ductility and low gloss potential for existing injection moulded TPO applications,” said Dave Mitchell, Dow Specialty Plastics & Elastomer's global market manager of transportation for thermoplastic applications. “In addition, they provide an opportunity to deliver the benefits of advanced TPO compounds to an expanded range of applications such as thermoformed sheets and flexible extrusion profiles.”

ENR 7487.00 Developmental POE is an ethylene-butene copolymer with a melt index of less than 0.5, Shore A hardness of 58 and density of 0.860 g/cm³. Dow said it is ideally suited for reduced-gloss TPOs, SEBS extension, flexible soft-touch compounds, wire and cable and impact modification.
