Dow ENGAGE™ HM 7387 Polyolefin
Categories:	Polymer; Thermoplastic; Polyolefin
Material Notes:	Product Description: ENGAGE™ HM 7387 Polyolefin Elastomer is an ethylene-butene copolymer that has higher molecular weight, better toughness, and higher melt strength than other commercially available polyolefin elastomers. It can serve as an extender for SEBS, impart lower gloss in hard TPOs, provide the basis for flexible soft-touch compounds, and is well suited for extruded applications such as wire and cable. It is also useful for impact modification of various thermoplastic resins. Main Characteristics: Pellet form High melt strength Improved toughness Applications: Polymer modification Extender for SEBS Soft-touch compounds Reduced gloss TPOs Wire and cable Impact modification Availability: Asia Pacific; Europe: Latin America; North America Form: Pellets Information provided by The Dow Chemical Company
