Abstract:
1. A flexible tube comprising: a first layer comprising a polyolefin material, wherein the first layer has a flexural modulus in a range of 10 MPa to 150 MPa; and a second layer directly bonded to and in direct contact with the first layer, the second layer comprising a blend of propylenic polymer and styrenic block copolymer, wherein the propylenic polymer has a melt flow index (MFR) of 0.1 to 35 dg/min and wherein the styrenic block polymer is selected from the group consisting of a hydrogenated styrene-butadiene-styrene block copolymer, a hydrogenated styrene-isoprene-styrene block copolymer, a styrene-ethylene-butylene-styrene block copolymer (SEBS), a styrene-ethylene-propylene-styrene block copolymer (SEPS), a styrene-ethylene-ethylene-butylene-styrene block copolymer (SEEBS), a styrene-ethylene-ethylene-propylene-styrene block copolymer (SEEPS), and any combination thereof; the blend having a loss tangent value (tan δ) at 25° C. of at least 0.1.
