Applications:

Heat shrink tubing is a type of extruded plastic tubing that can be cut to size and fitted over a wire or cable joint to protect and insulate the connection. When heat is applied, the tubing shrinks permanently, providing a protective seal. These polyolefin heat shrinkable tubes are very versatile and are used in both commercial and industrial applications for protecting and sealing cable joints and in-line components such as disconnect terminals and wire splices. They can also be used to carry out repairs on existing worn or torn cable or wiring insulation. Heat shrinks are commonly used for:

Electrical insulation

Environmental protection against moisture, dust, and chemicals

Mechanical protection to wires and small parts from abrasion

Mechanical strain relief on cable and connector joints to prevent damage caused by flexing or bending

Bundling and organizing harness wires, cable, and tubing

Colour coded identification of cables, wires, and component
