Utkarsh Permanently Lubricated (PLB) HDPE Duct pipes are made from virgin, UV grade HDPE materials and are used for deployment of Optic Fiber and Copper Cables. The ducts are manufactured as per TEC Standards & various international standards. The ducts have superior resistance to natural or mechanical damage. The PLB HDPE Ducts consist of two concentric layers, the outer layer being HDPE; co-extruded with an inner layer of solid permanent lubricant to reduce the Internal Co-efficient of Friction (ICF).
