WSD361 is a water blocking tape developed for longitudinal application directly under PE extruded jackets. This product maintains the fast swell and low mass of our original WSD351 material but uses and enhanced outer layer to provide a more stable surface to support the PE jacket during extrusion. The outer layer is a dense nonwoven with a cross linked binder system making it more resistant to the heat of extrusion and able to minimise PE jacket penetration.
