Specifications

Material: Outer: crosslinked 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;
  Semirigid 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.
