The heat shrink tubing is a shrinkable plastic tube which used to insulate wires. It provides abrasion resistance and environmental protection for electical works. We can use it for stranded and solid wire conductors, connections, joints and terminals in electrical wiring projects. And use it to repair the insulation on wires or to bundle them together, to protect wires or small parts from minor abrasion, and to create cable entry seals. Our 3:1 heat shrink tubing is made of polyolefin, which shrinks radially (but not longitudinally) when heated, to 1/3 of its diameter. All of our heat shrink tubings meet the requirment of CE, RoHS and UL, you can use it with full confidence.
