Abstract
The invention provides a composition suitable for use in pipe applications, the composition comprising: an ultra-high molecular weight ethylene-based polymer having an intrinsic viscosity from 5 to 50 deciliters/gram; a polyethylene resin comprising a first molecular weight ethylene-based polymer component and a second molecular weight ethylene-based polymer component, wherein the polyethylene resin has a density from 0.930 to 0.960 g/cc; a thermoplastic polyolefin elastomer having a density of from 0.850 to 0.910 g/cc; and, optionally, a fluoropolymer.
