ABSTRACT:
An antistatic hose for conveying fluids with at least one conductive layer (2) comprising a first, conductive material (3) and a second, non-conductive material (4). The first, conductive material (3) forms a basic matrix and medium sized blocks (5) of the second, non-conductive material (4) are inserted in the basic matrix of first, conductive material (3). The first, conductive material (3) forms a continuous conductive path (6) extending along the entire length of the hose (1). The second material (4) is distributed in the matrix of first material (3) in an uneven and irregular way. The first material (3) preferably comprises a thermoplastic material to which particles of a conductive material have been added, whilst the second material (4) is thermoplastic.
