Introduction
  Description

FlameRetardant Heavy Wall Adhesive-lined Heat Shrink Tubing is a polyolefin tubeextruded with a layer of hot melt adhesive as the inner layer. It has excellentinsulation, mechanical abrasion resistance, impact resistance performance andgood sealing performance against water and moisture.This product isfound in many applications esp. flame retardance demanding conditions likeinsulation and protection for high voltage cable middle connections,terminations and busbar as well as different kinds of pipelines for itsexcellent corrosion resistance, abrasion resistance. 

Features
