Water Blocking and Filling Yarn Between Optical Fiber Cable, Communication Cable

Product Name:Water Blocking Yarn1, Application:The water blocking yarn consists of industrial polyester filament, macromolecule swelling water absorbing tree ester and adhesive. It is mainly used for water blocking and filling between optical fiber cable, communication cable, fan-shaped wire core, power cable, submarine cable and other parts.Product Description2, PrincipleThe water block yarn consists two parts. One part is basing material, which is made of nylon or Polyester as reinforced rib to ensure the yarn to have better tensile strength and elongation.  The other part contains the expansion powder and fiber of polyacrylic ester,Which is super water absorption polymer, After absorbing the water, it will swell quickly to full the gap of cable to meet the purpose of water blocking.3,Standard : YD/T 1115.2-2001  Product Parameters4, Package:  In RollID:38mm/76mm/94mmOD:Max270mmQty./20FCL:5.5-6.5MT5,  Technical Specification                                                  SpecificationYarn density (Dtex)Basis weight (m/kg)Breaking strength (N)Elongation (%)Swelling rate (ml/g/1st min)Long-term thermal expansion rate (150ºC,24H,ml/g)Transient thermal expansion rate (230ºC,10min,ml/g)Water contain rate (150ºC,1min,%)700D78012857≥5015↓≥60≥65≥659↓1500D16706000≥5015↓≥60≥65≥659↓2000D22204500≥6015↓≥60≥65≥659↓2500D27803600≥7015↓≥60≥65≥659↓3000D33303000≥10015↓≥60≥65≥659↓4500D50002000≥15015↓≥55≥65≥659↓6000D66701500≥20015↓≥50≥55≥559↓9000D100001000≥25015↓≥45≥55≥559↓18000D20000500≥30015↓≥40≥50≥509↓  /* January 22, 2024 19:08:37 */!function(){function s(e,r){var a,o={};try{e&&e.split(",").forEach(function(e,t){e&&(a=e.match(/(.*?):(.*)$/))&&1
