CATV heat shrink tubeApplicationHeat Shrinkable Tubing and adhesive liner combination that established the CATV industry standard for splice and connector protectionFeaturesShrink ratio of 3.5 to 1An absolutely waterproof sealEnvironmentally seals and mechanically protectsAdhesive flows smoothly and will not dripSelective strip ability to meet CATV industry needsFast and simple installationMinimal heat required to produce error free installation without splittingHeat indicative paint ensures integrity of sealInstallation TestsWhen adequate heat is applied, heat reactive stripes change color: green to blackWhen color has changed, tubing is fully recovered, sealant has achieved balanced flow. Adhesive flows without dripping, No cracks or splitting, No surface charring during installationTemperature Rangeoperating temperature:-55℃ ~ 110℃Shrink temperature: 120℃Color BlackTechnical DetailsTest itemTest methodTypical valueTensile StrengthASTM D267112MpaElongationASTM D2671400%Specific GravityASTM D7921.15Elongation after Heat Aging(168 hrs at 150)ASTM D2671350%Tensile strength after heat agingASTM D267112MpaLow Temperature Flexibility(4 hrs at -55℃)ASTM D2671No crackingHardness (Shore D)ASTM D224060DHeat shock (4hrs at 200℃)ASTM D2671No cracking or flowingAdhesive Softening PointASTM-E2885Adhesive Peel Strength to P.E.ASTM D1000110N/25mmAdhesive Peel Strength to AluminumASTM D100080N/25mmDielectric StrengthASTM D267120kV/mmVolume ResistivityASTM D2571014Ω.cmCopper CorrosionASTM D2671No CorrosionWater AbsorptionASTM D5700.5%Fungus ResistanceASTM G21Specification:Product CodeIDbefore shrink(mm)I Dafter shrink(mm)Min.Wall thickness   After shrink(mm)Normal length/pc(meter)LK-12(12/4)1242.01.22LK-19(19/6)1962.51.22LK-25(25/6)2582.51.22LK-28(28/9)2892.51.22LK-33(33/8)33112.51.22LK-40(40/12)40122.51.22LK-45(45/12)43122.51.22LK-55(55/16)55162.71.22LK-75(75/22)75223.01.22
