Cable Materials
Underwater Cable Water-Blocking Tape
Boorim supplies textile-based water-blocking tape materials for underwater, submarine, offshore, and other moisture-sensitive cable applications where water migration control is critical.
Protection for Wet-Environment Cable Systems
Water-blocking tape is used inside cable structures to limit longitudinal water migration when an outer sheath or jacket is damaged. In underwater and offshore cable systems, this function is especially important because repair can be difficult, expensive, and time-sensitive.
The tape must combine reliable water-blocking behavior with the mechanical stability needed for cable production. Boorim focuses on clean handling, stable dimensions, roll quality, and textile construction choices that support smooth wrapping and consistent performance.
Key Performance Priorities
Water Migration Control
The material is designed to help slow or block water movement along the cable length after moisture exposure.
Swelling and Absorption Behavior
Water-blocking performance can be matched to the customer's swelling speed, absorption capacity, and test requirements.
Stable Cable Processing
Consistent width, thickness, roll winding, and tensile strength help the tape wrap smoothly on cable production lines.
Application Fit
Construction can be reviewed for submarine cable, offshore cable, power cable, communication cable, and other wet-environment designs.
Typical Applications
- Underwater and submarine cable water-blocking layers
- Offshore power and communication cable structures
- Longitudinal water migration control after jacket damage
- Moisture-sensitive cable designs requiring stable textile tape performance
Specification Points We Can Discuss
| Base construction | Woven, nonwoven, or composite textile structures can be reviewed according to cable design and processing needs. |
|---|---|
| Water-blocking behavior | Swelling speed, absorption capacity, gel stability, and water migration test targets can be discussed by application. |
| Dimensions | Width, thickness, roll length, and tolerance requirements can be aligned with cable wrapping equipment. |
| Mechanical properties | Tensile strength, elongation, flexibility, and handling behavior can be adjusted for stable production performance. |
| Roll and surface quality | Clean roll presentation, surface uniformity, edge quality, and low contamination are reviewed for reliable cable processing. |
