Key Players
Competitive Landscape
Competition in the water blocking tape market runs across three producer types: integrated nonwoven manufacturers, specialist swellable-tape producers and strand-blocking material companies. The field remains fragmented as power-cable screens and optical cores require different material behavior, and qualification records raise switching costs once a tape enters serial production.
Investment has moved toward cable capacity and processing routes that increase qualification demand for long power-cable programs. Prysmian completed its Pikkala submarine cable factory expansion in May 2025, adding a 525 kV HVDC line capable of producing about one kilometer of cable per day. NKT brought new medium-voltage lines into operation in January 2025 at its Czech and Swedish sites. Tape companies now compete on repeatable properties and technical support across longer production campaigns.
Company developments mapped to drivers, trends and opportunities (2026-2036)
| Development | Driver | Trend | Opportunity |
|---|---|---|---|
| In May 2025, Prysmian completed its Pikkala expansion with a 525 kV HVDC line able to produce about one kilometer of submarine cable per day. | Long HVDC campaigns increase demand for qualified moisture barriers that remain consistent across extended cable lengths. | Submarine cable capacity is concentrating in factories built for 525 kV programs and long continuous production runs. | Early tape qualification on new lines provides a route to recurring conductive and salt-water grade orders. |
| In February 2025, Sumitomo Electric UK Power Cables marked first structural steel at its Port of Nigg submarine cable factory planned to open by mid-2026. | Planned UK subsea production requires local material qualification as the factory approaches routine commercial output. | New submarine cable capacity is moving closer to North Sea projects and regional supply chains. | Early material trials provide a route into serial production once the planned factory becomes operational. |
| In January 2025, NKT made new medium-voltage cable lines operational at its Czech and Swedish sites to increase capacity and capabilities. | Grid customers require more medium-voltage cable volume without extending delivery schedules. | European manufacturers are adding regional medium-voltage capacity alongside larger high-voltage and submarine investments. | Water-blocking materials gain repeat volume once they clear line trials on newly commissioned cable equipment. |
Competitors not mapped in the development table include Lantor, Geca Tapes, Fori Group, Nantong Siber Communication, Ekstel, Chase Corporation, Loypos Corporation and Freudenberg Performance Materials across nonwoven tapes, woven semi-conductive tapes and strand-blocking materials.

Which suppliers have documented qualification or quality approvals?
Lantor reports ISO 9001 certification for its Veenendaal manufacturing base and Ekstel reports ISO 9001 plus ISO 14001 certification. Loypos Corporation holds valid International EPDs for several semi-conductive woven water-blocking tapes.
Which companies provide power-cable water-blocking products?
Geca Tapes and Freudenberg Performance Materials document water-blocking materials for medium-voltage and high-voltage cables. Chase Corporation supplies strand-blocking compounds while Loypos Corporation documents woven semi-conductive tapes for screened power-cable layers.
Which suppliers serve Europe and North America?
Freudenberg Performance Materials and Geca Tapes document international cable supply from European production. Chase Corporation serves North American cable applications while Lantor manufactures cable-protection materials from its Netherlands operating base.

Research Methodology
The companies mapped here illustrate how the water blocking tape market is structured rather than providing an exhaustive ranking. Inclusion requires current verifiable evidence that a company supplies swellable cable tape or a directly competing strand-blocking material within the defined moisture-protection scope. Company announcements and public corporate records establish current activity. Qualification records and environmental product declarations confirm product-level status for named cable materials. Capabilities are assigned to the documented cable-material platform instead of extending them across unrelated parent-company products. Market-share estimates remain proprietary FMI assessments for the 2026 to 2036 forecast period.
