<p>A flexible hose, particularly for transporting food liquids, comprising a t least one outer protective layer (2) of a first flexible polymer material (A) and at least one inner layer (3) of a second flexible polymer material ( B). The second polymer material (B) comprises a thermoplastic compound (C1 ) of polyolefin nature and an elastomer compound (C2) in such a weight percen tage as to impart a Shore A hardness of less than 85. Also, the second polym er material (B) is selected from polymer materials substantially free of liq uid plasticizer agents.</p> |
