WATER BLOCKING FLAT YARNS
Water Blocking Flat Yarns
Water Blocking Flat Yarns has superabsorbent properties (SAP), designed to quickly and efficiently block the longitudinal migration of water within the cable. Upon contact with moisture, it expands to create a physical barrier that protects internal components from corrosion, degradation, and signal loss.
Water blocking flat yarnsApplication
Its flat geometry allows for uniform distribution without increasing the cable diameter, making it ideal for compact designs. Additionally, as it is a dry solution, it eliminates the need for blocking gels, facilitating cleaner and faster splicing processes.
