Water Blocking Tape/Water Swellable Tape
S&A presents water blocking tape, also known as water swellable tape, designed to provide superior water blocking performance for power cables, communication cables, and other applications. Our tape is manufactured using polyester non-woven fabric, adhesive, and high-speed expanding polymer water-absorbing resin.
Features
- Excellent Water Blocking: The tape's exceptional water blocking performance comes from the highly absorbent resin, which quickly absorbs and expands upon contact with water.
- Cable Longevity: By preventing the ingress of water and moisture, our water blocking tape enhances the operational lifespan of cables.
- Corrosion Resistance: It effectively minimizes water and moisture-related corrosion in cables.
