Typical Applications:

Primarily used to block the longitudinal flow of moisture in a cable. Water blocking shielding tapes offer the additional benefit of RF/EMI shielding. Click here to view a white paper on characterizing and selecting superabsorbant cable components.

Construction

• Single layer nonwoven polyester fabrics with proprietary NEPTCO water blocking coating on one side
• Shielding tape laminates with proprietary NEPTCO water blocking coating on one or both sides

Features/Benefits

• Single layer product eliminates the possibility of delamination. Thinner profile allows longer lengths of tape per pad.
• Unrestricted gel flow into cable interstices allows for more effective blocking
• Rapid gel formation attains full swell capacity in seconds
• Superior adhesion of coating to non-woven helps reduce powder fall-out in the cable manufacturing process.
