Thermoplastic Vulcanizate Conduits for Transporting Hydrocarbon Fluids

A flexible conduit comprising:

• (a) an inner housing;
• (b) at least one reinforcing layer at least partially disposed around the inner housing;
• (c) an outer protective sheath at least partially disposed around the at least one reinforcing layer;
• and
• (d) a thermally insulating layer disposed between the at least one reinforcing layer and the outer protective sheath,
• wherein the thermally insulating layer comprises a thermoplastic vulcanizate composition comprising:
• (i) a dispersed phase of an at least partially cured rubber comprising repeating units derived from at least one C4 to C7 isomonoolefin monomer and (ii) a continuous phase including at least one thermoplastic polymer.
