Water Swellable tapes are designed to prevent water ingress into fibre optic, copper data/telecom and power cables.

Using superior super absorbent polymers (SAP) gives these tapes premium performance during the critical first minute of response to water. The SAP is laminated and evenly distributed between various non-woven materials so that all the SAP contributes efficiently to the water blocking properties of the tape. Water swell-able tapes are available in insulative, semi-conductive, laminated and marine versions to suit the cable application.
