Introduction
  Description


Semirigid medium wall adhesive-lined heat shrink tubingis made of semirigid polyolefin extruded with a layer of hot melt adhesiveinside. This product carries excellent insulation and sealing, corrosionresistance performance, and are found in wide applications like insulation andprotection of medium and low voltage cable middle connections and terminations, busbars, as well as different kinds of pipelines because of its excellentcorrosion resistance, moisture-proof, and abrasion resistance performances.
