Water Blocking Insulation Tape for Wire and Cable Manufacture

Product Name:Water-blocking Tape1, Application and Feature: It is a combination of tape, yarn, or coating to prevent longitudinal penetration of water into the cable core .The main principle is to use a kind of polymer that can absorb water and quickly form gel to fill the seepage channel through the expansion of hydrogel. It is widely used In optical fiber cable, data cable, telecom cable and control cable.Proven high performance of swelling and water blocking Process friendly REACH and RoHS compliant 2, Section Diagram:   Single Sizes   Double sizes3,PackageIn Roll  ID 76mm-105mm4,Technical Parameter:   Single Side Non-conductivity Thickness MassPer AreaTensile StrengthElong-AtionSwellingSpeedSwellingHeightShort Term StabilityLong Term StabilityMoistureContentmmg/m2N/cm%mm/1,0mm/3,0ºCºC%0.1±0.0140±5≥18≥12≥3≥423090≤60.15±0.0360±5≥20≥12≥5≥823090≤60.18±0.0365±5≥25≥12≥6≥923090≤60.20±0.0370±10≥30≥12≥12≥1223090≤60.25±0.0380±10≥30≥12≥12≥1223090≤60.30±0.0390±10≥35≥12≥12≥1223090≤6Double Side Non-conductivity Thickness MassPer AreaTensile StrengthElong-AtionSwellingSpeedSwellingHeightShort Term StabilityLong Term StabilityMoistureContentmmg/m2N/cm%mm/1,0mm/3,0ºCºC%0.18±0.0165±10≥25≥12≥4≥623090≤60.20±0.0370±10≥28≥12≥6≥923090≤60.25±0.0380±10≥35≥12≥8≥1223090≤60.30±0.0390±10≥40≥12≥10≥1423090≤60.35±0.03100±10≥40≥12≥10≥1423090≤60.20±0.0375±10≥35≥12≥10≥1223090≤60.25±0.0385±10≥35≥12≥12≥1523090≤60.50±0.03130±10≥45≥12≥12≥1623090≤6Single Side Semi-conductivity Thickness MassPer AreaTensile Strength Elong-Ation SwellingSpeed SwellingHeight SurfaceResistance VolumeResistance MoistureContent mmg/m2N/cm%mm/1,0mm/3,0ΩΩ.cm%0.25±0.0390±5≥25≥12≥6≥8≤1500
