Material Notes:

Description: ENR 7380.00 is a revolutionary new ethylene-butene copolymer with 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. ENR 7380 is also useful for impact modification of various thermoplastic resins.Information provided by manufacturer.This former DuPont Dow Elastomers product line is now produced by Dow Chemical.
