Heat shrink tubing is commonly used for connecting electrical cables, insulating soldered points in resistors and capacitors, marking and protecting electrical cables, preventing corrosion of metal rods or pipes, and protecting antennas. These waterproof heat shrink tubes are used for connecting fiber optic cables.

The halogen-free, flexible, and flame-retardant heat shrink tubing does not contain harmful substances such as Pb, Cd, Hg, Cr+6, PBB, and PBDE. It can be used in any enclosed space where a flame-retardant, halogen-free environment is required, such as in subways, skyscrapers, transport, and cargo ships. It is UL certified for 600V and carries the F-mark.
