PE-M has a relatively narrow molecular weight distribution, exceptionally high toughness, excellent optical properties, and a uniform comonomer content. Because of the narrow molecular weight distribution it behaves less as a pseudoplastic (especially under larger shear rates). polyethylene (PE), light, versatile synthetic resin made from the polymerization of ethylene. Polyethylene is a member of the important family of polyolefin resins.
