Plastic pipes for protecting cables in the ground are available in a wide variety of diameters and wall thicknesses. To ensure that the cables inside the pipe are protected from environmental influence and damage, appropriate standards must be met that clearly specify the properties of the conduit.

Among other things, these standards specify the diameter/wall thickness ratio, which fixes the amount of material per running metre of pipe. To save costs, recycled materials are often used, but their property profiles and processing characteristics are dependent on the batch. Another approach to reducing costs and plastic consumption is to physically foam the pipes. Environmentally friendly gases are injected into the plastic and mixed with it in the extruder. In the subsequent pipe extrusion process, these gases form a fine pored foam that leads to weight reduction and savings in plastic. Promix Solutions offers key technologies in the area of mixing, foaming and cooling to the plastics processing and polymer production industry, including foam extrusion systems.
