Product Description

Water blocking tape or Swelling Tape is a modern high-tech water-blocking material with the function of water-absorbing and expansion, which is composed of polyester fiber non-woven fabric and high-speed swelling water-absorbent resin. The excellent water-blocking performance of the water blocking tape mainly comes from the strong water-absorbing performance of the high-speed expansion water-absorbent resin that is evenly distributed inside the product. The polyester fiber non-woven fabric to which the high-speed expansion water-absorbent resin adheres ensures that the water blocking tape has sufficient tensile strength and good longitudinal elongation. At the same time, the good permeability of polyester fiber non-woven fabric makes the water blocking tape expand immediately when exposed to water, and the water-blocking performance is effectively guaranteed for our Swelling Tape.

Application

Mainly used to coat the core of communication optical cable, communication cable and power cable to play the role of binding and water-blocking Swelling Tape.
