Material:

Outer: cross-linked modified semi-rigid polyolefin resin
Inner layer: hot melt adhesive
Shrink ratio: 4: 1

Features:

  • Higher shrink ratio, for the quilt was larger diameter coverage;
  • Transparent;
  • Semi-rigid polyolefin material, higher mechanical properties and wear resistance,perform stress harness connector and terminal solutions at an excellent abrasion resistance and protection;
  • Thicker layer of hot-melt adhesive, having excellent sealing performance,effectively resist fluid and moisture intrusion;
  • Excellent oil resistance, particularly suitable for automotive interior environments; 
  • Operating temperature: -40 ℃ ~ + 130 ℃, applicable to a wider temperature range;
  • Start shrink temperature: 110 ℃, full recovery temperature: 135 ℃.

Applications: This product is designed for automotive wire harness and piping requirements and specific design, it can be widely used with visual requirements of a variety of automotive wiring harness insulation seals, and other lines and terminals at the resumed indirect local stress relief and abrasion performance protection.
