water blocking yarn 2500D for optical calbe

Blocking yarn is an optical cable water-blocking material, made by swelling fibers. expansion coefficient, good water-blocking effect, and high tensile strength, free acid, on the cable material no compatibility impact, can replace the tie yarns (tape), filling gel and waterproof tape, optical cable provides new protective material. The material can be used as filler for the cable core rope structure, can also be in different ways around the cable core and between the sheath size. Because of its excellent water-blocking and sealing performance, when moisture or water penetration into the cable, the water-blocking yarn has fast swelling, and clogging water into all channels within the cable, so as to achieve complete sealing and water-blocking effect. according to the thickness it has a variety of different models, with a stable structure, easy to use, reliable water resistance, environmental clean, no oil pollution and cable light weight advantages. using this material for optical cable production technology, improve product quality, reduce production costs optical cable provides an ideal way.
