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

These highly flexible heat shrink tubes made of polyolefin feature a smooth outer surface and a thin wall. They offer excellent tensile strength and a shrink ratio of up to 50%. The material is flame-retardant, and water absorption is limited.
