Introduction
  Description


Semi rigid heavy wall adhesive lined heat shrink tubing is made of polyolefin materials extruded with a layer of hot melt adhesive inside. This product carries excellent insulation and sealing, corrosion resistance performance, with which it was found in wide applications like insulations and protections for high voltage cable middle connections and terminations , busbars, as well as different kinds of pipelines because of its excellent corrosion resistance, moisture-proof, and abrasion resistance performances.
