Produced with PTFE resins characterised by low microporosity and high tensile strength, the convoluted tubes and hoses of polyhose are the right answer for the transport of gas, fluids and chemicals where the bending radius requires a high flexibility together with a low permeability.
The helicoidal profile has been studied to avoid blockages of the passing fluids and their consequent solidification and it makes them easily washable and sterilizable.
The wide range of temperature (from -73'C to 260'C) reachable by our tubes allow them to be the right solution for many industrial and technical processes. Their high resistance to the peroxides, present in the normal rubber hoses, makes them the obliged choice for the car, motorcycle and shipyards industries. In the shipyard our pare utilised for the fabrication of flexible hoses to use on ships and boats.
