Data center developers in Virginia, Texas and Arizona specify armored, water-resistant cables for campus interconnects, and state broadband programs are directing funds to fiber builds in rural areas where buried and aerial installations face moisture and freezing risk. Utility undergrounding programs in wildfire-prone and storm-affected states add further orders for medium voltage cables incorporating semi-conductive tapes.

⮞In September 2026, Lightera, part of Furukawa Electric Group, announced investments across plants in Brøndby, Denmark, and Norcross, Georgia, and Sturbridge, Massachusetts, intended to nearly triple its submarine optical-fiber manufacturing capacity by 2029. The company cited demand from artificial intelligence computing, hyperscale data centers and cloud services, which also increases consumption of the cable components, including water-blocking tapes, that surround the fiber.

Water Blocking Tapes Market Segment Analysis

By Type, Non-Conductive Water Blocking Tapes Dominate Water Blocking Tapes Market; Semi-Conductive Water Blocking Tapes to Register Fastest Growth.

Non-conductive water blocking tapes dominate the Water Blocking Tapes Market because of the extensive application of these tapes in the power cables, telecommunication cables, and optical fiber cables. Moisture protection is crucial in these cables to ensure insulation effectiveness and efficient performance. They help in the prevention of longitudinal movement of water and minimize risks of cable damage as well as provide extended service life. The ability to be used in different types of cables increases their demand in infrastructure uses.

Semi-conductive water blocking tapes are projected to register the fastest growth, owing to the growing preference for high voltage and extra-high voltage power cables.

Market Dynamics

Growth Drivers: Fiber Rollouts, Subsea Cables and Grid Modernization

Growing FTTH installations, 5G transport networks, and data centers connectivity have increased the use of water blocking tapes in outdoor optical fibers and communication cables. Growing numbers of fibers and cable sizes call for lightweight and rapidly swelling tapes that prevent water ingress longitudinally but allow maintaining the flexibility of the cable. The combination of such requirements allows special tape producers to develop more advanced materials for future telecommunication networks.

Furthermore, offshore wind farms, cross-border electricity interconnector solutions, and newly constructed submarine communication networks will increase the demand for efficient underwater and subsea cables and their installations. At the same time, grid modernization projects increase the number of underground power cable installations in order to increase the reliability of the electricity grids and protection against environmental effects on cables. Such projects require moisture protection of the cable conductors, insulation, and other internal elements. Therefore, there is potential growth in the demand for semi-conductive and non-conductive water blocking tapes in the context of telecommunications, renewable energy infrastructure, and electricity transmission networks.

Restraints: Raw Material Costs and Substitution by Yarns and Gels

The variation in prices of super absorbent polymers, polyester fibers, non-woven backing materials and other petroleum-based raw materials used in the manufacturing process may lead to an increase in the cost of production. There is also a risk of increased manufacturing costs for manufacturers working with the cable producers through long-term supply arrangements due to inability to transfer price increases. Consistent swelling capacity, dimensional stability and tensile strength require strict quality assurance resulting in higher costs of production.

Furthermore, there is competition from other moisture protection solutions like water swellable yarns, dry core solution, gels and floodings. These materials are selected by the cable manufacturers based on design features of cables, performance needs, ease of manufacture and raw material costs. Yarn-based products are used in some optical fiber cables leading to less need for tape products hence reduced demand. Extended material qualification process and strict testing procedures make the acceptance process more complex. The fluctuating telecommunication capital expenditures and cable manufacturing volumes may introduce additional risks into the business environment.

Opportunities: Halogen-Free Constructions, Submarine Systems and Multifunctional Tapes

Increasing demands for safer and environmentally friendly cables represent potential markets for producers who manufacture halogen-free, low smoke, and corrosion-resistant water-blocking tapes. Today, data centers, railways, tunnels, commercial real estate, and utility operators demand cables which would satisfy certain fire-safety requirements and perform well in a specific environment. Producers who can develop materials with reliable and compatible properties and consistent swelling behavior can benefit from market opportunities due to differentiation and contracts.

Submarine telecommunication network, off-shore wind farms, and submarine inter-connectors represent another attractive opportunity since these projects require highly reliable cables that can provide effective water blocking throughout their lifespan. Producers can target premium projects by developing materials with higher water-absorption properties, faster swelling rate, and mechanical reliability. Also, multifunctional materials, which provide not only water-blocking but also mechanical reinforcement, electrical stress controlling, or improved processing properties can help cable manufacturers to eliminate certain number of material layers.

Recent Developments:

• In early 2024, Chase Corporation expanded its U.S. plant to meet demand for its CableSeal product line of water-blocking materials for wire and cable manufacturers.
