What is Water Blocking Tape?
Water blocking tapes and water swellable tapes prevent the progression of water deep into many types of critical cable designs.
Applications for Water Blocking Tape, Water Swellable Tape
Water blocking tapes and water swellable tapes rapidly absorb liquid at the point of insulation failure and quickly swell to block any further ingress. This ensures any cable damage is minimised, fully contained and is easy to locate and repair. Examples of applications where Scapa’s water-blocking tapes are used include:

Product Benefits of Water Blocking Tape, Water Swellable Tape
Water blocking tapes and water swellable tapes offer premium performance benefits during the critical first minute of response to water. The use and blending of superior super absorbent polymers (SAP) contributes significantly to enhanced performance. Some of the features and benefits of using water-blocking tapes are:
• Seawater blocking capability
• Fast swell
• Suitable for direct fibre contact
• High yield
• Suitable for fast processing
• Low electrical resistance
• Good cushioning properties
• Asymmetric swell if required
• Proven long term performance
Swellable Tape is a non or semi conductive, non-woven and double sided swelling tape which contain super absorbent resin in natural white color and carbon impregnation black color.
DijitalPort provide super absorbent resin to high swelling rate on both side as equally and high tear strength performance for better process conditions.
Non-conductive water blocking tapes are widely using for bedding, separation and water blocking properties for fiber optic and special cables.
Semi-conductivity feature have been made by carbon impregnation on surface of non-woven material and final color became black.
