This product is a type of tubing, often made from polyolefin, designed to shrink tightly around wires or cables when exposed to heat. The resulting insulation provides mechanical protection, electrical insulation, and environmental sealing. For example, it can be used to repair damaged wiring, bundle cables together for organization, or provide strain relief at connection points.
The utility of this material is significant in numerous applications, spanning from basic household electrical repairs to complex industrial wiring systems. Its ability to create a durable, protective barrier enhances the longevity and safety of electrical connections. Historically, this type of insulation replaced methods like electrical tape, offering a more robust and permanent solution.
