Abstract
The present invention provides a multi-layer hose comprising a cover layer, comprising a first polymer, an enhancement layer comprising woven filaments, and an inner lining, comprising a second polymer, wherein the first polymer and the second polymer are dissimilar. The first polymer is preferably a polymer with good wear resistance properties, e.g., thermoplastic polyurethane (TPU), TPU/PVC, or PVC, or PVC/NBR. The second polymer is preferably a polymer with good chemical resistance properties, e.g., ethylene propylene diene monomer (EPDM) rubber. The present invention also provides a method of manufacturing said multi-layer hose.
