Swelling Tape

Water blocking 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.
