Water Blocking Tape Manufacturers and
Suppliers in India
Polytape is a specialist water blocking tape manufacturer in India,
producing Water Blocking Tape (WBT) used to prevent longitudinal water ingress in fiber optic and
power cables. As a trusted water blocking tape supplier, we manufacture both semi-conductive
and non-conductive tape constructions to match the electrical and mechanical requirements of different
cable designs.
Our product range includes:
- Semi-conductive water blocking tape- designed for power cable applications where controlled
conductivity is required alongside water-blocking performance, making Polytape a dependable
semi-conductive tape for power cable manufacturers
- Non-conductive WB tape- engineered for fiber optic and dielectric cable designs where
electrical insulation must be maintained while still blocking water migration
- Fiber optic cable water blocking tape- swellable tape wrapped around the cable core or
beneath the jacket to swell on contact with moisture and seal against water ingress
As a non-conductive WB tape manufacturer, our tapes swell rapidly on contact with water,
sealing the cable core and preventing water from travelling along the cable length toward splice
enclosures and joints - protecting signal integrity and cable lifespan in duct, direct-burial, and
aerial installations.
Key features:
- Rapid swell rate on contact with water for effective sealing
- Available in semi-conductive and non-conductive constructions
- Compatible with fiber optic and power cable manufacturing processes
- Consistent tape width, thickness and swell performance for reliable production-line application
