Products Description
Electrical Insulation Heat Shrink Tube is a heat-shrinkable tubing material with excellent electrical insulation properties. It is primarily used for insulation, protection, and sealing of cable and wire connections. Upon heating (typically around 120°C), it rapidly shrinks radially to half its original diameter or even smaller, tightly wrapping around the cable or connector surface, providing reliable electrical insulation, mechanical protection, waterproof sealing, and flame retardancy.
