Cable Wrapping Water Blocking Nonwoven Fabric Tape — Manufacturer India
Cable Wrapping Water Blocking Nonwoven Fabric Tape is a critical B2B raw material supplied by Favourite Fab — a manufacturer-direct nonwoven fabric source serving industrial OEMs, hygiene converters, and export buyers across 50+ countries from Agra, India.
What Is Cable Wrapping Water Blocking Nonwoven Fabric Tape
Water-blocking nonwoven tape is a critical component in underground and submarine telecom + power cables. The PET nonwoven carrier holds a superabsorbent polymer (SAP) layer that swells on water contact — sealing cable cores against longitudinal water ingress. Used in fibre optic, LV/MV power, and offshore wind-farm cabling.

Frequently Asked Questions
Q: What swell speed and height does the tape achieve?
A: Standard grade swells to ≥10 mm height within 60 seconds of water exposure. Premium grades reach 15 mm in 30 seconds. Test method per IEC 60840 Annex E water-tightness.
Q: Is the tape compatible with LSZH cables?
A: Yes. SAP coating and PET nonwoven are halogen-free. Acid-gas emission per IEC 60754-1 = 0%. Smoke density per IEC 61034-2 well within LSZH limits.
Q: What cable types use water-blocking tape?
A: OPGW fibre optic, LV/MV power cables (XLPE-insulated), submarine cables (wind farm interconnects), telecom trunk cables. Wrap or longitudinal-lay installation.
Q: Can you supply double-sided tape?
A: Yes. Single-sided (PET base + SAP on one face) and double-sided (SAP on both faces) variants available. Double-sided used in armoured cable applications.
Q: Minimum order quantity?
A: MOQ is 1,000 km per width / grade. Sample rolls 100 m provided for cable-line trial.
Q: Do you supply both wrap-tape and yarn formats?
A: Yes. Slit-width wrap tape (10–100 mm) and water-blocking yarn (extruded SAP-coated PET monofilament) both available.

B2B Applications & OEM Use-Cases
- Power Cable Manufacturers: High-voltage power cable OEMs (11 kV to 400 kV) source our IEC 60684-3 compliant PET/glass nonwoven tapes for conductor bedding, armour bedding, and core wrapping layers that require consistent dielectric strength (≥10 kV/mm) and dimensional stability during cable stranding and jacketing processes.
- Fibre Optic Cable Producers: Fibre optic cable manufacturers use our SAP-coated water-blocking nonwoven tape as the longitudinal water-blocking layer around buffer tubes, replacing flooding compounds with a clean, dry, recyclable alternative that meets Telcordia GR-20 and IEC 60794 water-blocking requirements.
- Automotive Wiring Harness Assemblers: Automotive wiring harness manufacturers use slit PET nonwoven tape (10–50 mm width) for bundling, abrasion protection, and noise damping in engine bays and door harnesses, where the tape must withstand 130°C continuous operating temperature and resist vibration-induced abrasion.

Frequently Asked Questions
What is the difference between water-swelling and water-blocking nonwoven tape?
Water-swelling tape contains superabsorbent polymer (SAP) particles that absorb water and swell to form a gel barrier — this is the dominant mechanism in modern dry water-blocking cables. Traditional water-blocking relied on flooding compound (petroleum jelly) that filled voids mechanically. SAP-based nonwoven tape is cleaner, lighter, recyclable, and compatible with dry cable designs. Favourite Fab supplies both plain dielectric PET nonwoven and SAP-coated water-blocking variants.
Why is dielectric strength important for cable-wrapping nonwoven?
In high-voltage power cables, the nonwoven bedding and wrapping layers are part of the insulation system. Any breakdown of the wrapping material under voltage stress can create a leakage path leading to partial discharge, insulation degradation, and cable failure. A dielectric strength of ≥10 kV/mm ensures the nonwoven layer maintains its insulating function at the operating field strengths encountered in medium and high-voltage cables.
Can cable-wrapping nonwoven tape be supplied on traverse-wound bobbins?
Yes. Slit nonwoven tape can be supplied on traverse-wound bobbins in widths from 10 mm to 150 mm, optimised for automatic taping heads on cable stranding and extrusion lines. Bobbin core diameter, flanged or flangeless, and traverse pitch can be specified to match your taping machine requirements. Please provide your taping machine make and model for a tailored winding specification.
