Water blocking

Water-blocking binder yarn is specifically designed to act as a binding agent for optical fibers within fiber optic cables. The primary feature of this product lies in its capability to absorb and impede the propagation of water inside the cable, ensuring maximum protection and dependable performance for fiber optic networks. In addition to its water-blocking function, the engineered binder yarn for water blocking is designed with low, super low, and ultra-low shrinkage to prevent excessive pressure or compression, thereby maintaining signal quality and integrity throughout the lifetime of the fiber optic cable.
A high-tenacity polyester multifilament yarn is precisely wound to facilitate high-speed binding on SZ-stranded optical fibers.
