Thin-walled microducts MTB Micro MC

Thin-walled microducts MTB Micro MC are designed to fill already existing secondary tele-technical canalization, and to fill cable pipelines, including pipes partly occupied by the fiber optic cable. Made of high density polyethylene HDPE, with smooth inner surface (for diameters < 7mm) or longitudinally grooved inner surface (for diameters > 7mm). Co-extruded inner surface is made of slippery material, with a very low coefficient of friction. Produced in full color or semi- transparent to facilitate the recognition of microducts filled with cables.
