Cable Tapes

Water blocking tape (Non Conductive)

The double-side non-conductive laminated water-blocking tape are composed of polyester non-woven fabric, polyacrylate swelling powder, along with corrosion inhibitor. It is an excellent replacement of flooding compound, under radial barriers, water blocking armouring/between cable components, replacement of flooding compound in loose tube constructions and in slotted core designs/water-blocking reinforcement layers.
