Product specifications

8/4.4mm single UV resistant microducts are designed for long term protection of fiber optical cables and are especially suitable for installation of micro cables. Direct Bury/UV resistance for 20 years type of microducts are thick wall products that attain their mechanical robustness and functional performance through their intrinsic thick walls and need no further protection in underground or outdoor installations. The microduct are made of high-density virgin polyethylene (HDPE). Every microduct has a permanent, co-extruded silicone compound inner liner and longitudinal grooves giving a coefficient of friction of less than 0,1.
