Beschreibung
Zusammenfassung:	Embodiments of the present disclosure include composites and flexible multilayer pipe liners comprising a fibrous layer; and a polyolefin backing layer comprising a blend of: (a) an ultra-high molecular weight ethylene-based polymer having an intrinsic viscosity from 5 to 50 deciliters/gram, (b) 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; (c) a thermoplastic polyolefin elastomer having a density of from 0.850 to 0.910 g/cc; and (d) optionally, a fluoropolymer.
