Heat shrinkable identification continuous flattened tubing is used in the identification of wires and cables by computer-based printing onto the tube. White thin-wall, flame retarded radiation cross-linked modified polyolefin is flattened (8mm wide) and spooled. Tubing can also provide terminal insulation and strain relief. Suitable for a variety of applications, where wiring system complexity is relatively low. Has a 3:1 shrink ratio.
