DUWAI DWIS-ES - Adhesive Heat Shrinkable Tubing for Automotive
APPLICATIONS
DWIS-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: -55℃ ~ 130℃
- Minimum shrink temperature: 135℃
- Full recovery temperature: Above 135˚C
COLOR
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
