MULTILAYER FLEXIBLE TUBING

摘要

PROBLEM TO BE SOLVED: To provide flexible tubing that reduces environmental and health concerns associated with PVC-based flexible compositions.SOLUTION: A hose may have two or more layers. A flexible tube 200, which is flexible tubing including a bulk layer 202 and a liner 204, includes a first layer 204 comprising a polyolefin material having a flexural modulus of not greater than 150 MPa and includes a second layer 202 directly bonded to and in direct contact with the first layer 204. The second layer 202 comprises a blend of propylenic polymer and styrenic block copolymer.
