A flexible conduit used for transportation of hydrocarbon fluids for off-shore and on-shore oil and gas applications includes an inner pressure sheath, at least one reinforcing layer at least partially disposed around the pressure sheath, an outer protective sheath at least partially disposed around the at least one reinforcing layer, and optionally a thermally insulating layer disposed between the at least one reinforcing layer and the outer protective sheath. At least one of the inner pressure sheath, outer protective sheath, and the thermally insulating layer is manufactured using a thermoplastic blend (TPB) composition. The TPB compositions disclosed herein are useful for the formation of at least one polymer layer of the thermoplastic umbilical hoses used for transportation of hydrocarbon fluids.

A conduit, particularly flexible conduit comprises an inner tubular housing, at least one reinforcing layer at least partially disposed around the inner housing, an outer protective sheath at least partially disposed around the at least one reinforcing layer, and optionally a thermally insulating layer disposed between the at least one reinforcing layer and the outer protective sheath. At least one of the outer protective sheath and the thermally insulating layer comprises a thermoplastic vulcanizate composition.

A crack-resistant article comprising a diene terpolymer, the diene terpolymer comprising (or consisting essentially of) from 0.01 wt % to 10.0 wt % diene derived units, and 1.0 wt % to 20 wt % of Cto C&#x3b1;-olefin derived units based on the weight of the diene terpolymer, wherein the diene terpolymer: a) has a g'of less than 0.90; b) has an Mw within a range of from 100,000 g/mol to 500,000 g/mol; c) has an Mw/Mn within the range of from 3.5 to 12.0; and d) an Mz/Mn of greater than 7.0. Inventive articles comprise a blend of a relatively high density linear polyethylene and the diene terpolymer.
