AIS-ES - Adhesive Heat Shrinkable Tubing for Automotive

-40~+130 MinShrink110 Shrink4:1 Fireproof Uvproof Rainproof RoHS


AIS-ES is a waterproof heat shrinkable tubing for automotive wire harnesses. It is specially designed for wire harness insulation and waterproofing in the automotive industry. The higher 4:1 shrink ratio and high temperature resistance polyamide hot melt adhesive can fully resist water and protect the wire harness from corrosion and moisture. The outer layer is made of semi-rigid and abrasion resistant polyolefin, providing full protection for harsh environments in automotive.

Operating Temperature Range

  • Continuous operating temperature: -40℃ ~ 130℃
  • Minimum shrink temperature: 110℃
  • Full recovery temperature: Above 135˚C


Standard color: black, (Other colors, special sizes, and cut pieces are available on request.)


  • 4:1 high shrink ratio
  • Excellent watertight seal
  • Semi-rigid, abrasion resistant and flame retardant material
  • Resistant to common solvent
  • Compliance with RoHS and REACH environmental regulations
