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

This is a halogen-free, flexible, flame-retardant heat shrink tubing that is manufactured without lead, cadmium, mercury, chromium (VI), 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, transportation vehicles, and cargo ships. It meets UL 600V and F-marking standards.
