Heat-shrinkable tubing is a flexible heat shrinkable tubing desingned for the commercial market. The typical properties are flame-retardant,good resistance to common fluids and solvents and a high dielectric strengh. So it is suitable for a wide range of applications,including electrical insulation,strain relief,cable bonding,color-coding and identification of wires.cables,pipes,and electrical and electronic components. Specification ValuesOperating Temperature: -55 125 CShrinking Temperature: Start at 70 C, and shrunk totally at 110 C(CB). Size range: 0.6 180mm , special size are negotiable.
