WATER BLOCKING TAPES
Water BlockingTapes
Water Blocking Tapes contains superabsorbent polymers (SAP) that swell upon contact with water. Their function is to block longitudinal moisture penetration inside the cable. They ensure protection of internal components and stable performance. Applied in HV/MV power, f iber optic, data, telecom, and special cables.

Range of products
Non-conductive Water Blocking Tape: single and double layer.
Semi-conductive Water Blocking Tape: single and double layer.
Reinforced Non-conductive Water Blocking Tape.
Reinforced Semi-conductive Water Blocking Tape.
Key Benefits
Water Blocking Tapes are specialized protective components used in the construction of power, data, and telecommunication cables. They are composed of non-woven or woven substrates impregnated with super-absorbent materials (SAP – Super Absorbent Polymers) that rapidly swell upon contact with water. This swelling effect blocks and seals the cable core or interstices, preventing longitudinal water penetration inside the cable structure.
Key features
- Non-conductive and Semi-conductive performance.
- High water swelling speed for different requirements.
- Low weight. High strength for helical application.
- Thickness from 0.1 mm to 0.3 mm.
- Presented in various forms: Pads, Spools and Jumbo Spools.
