Material:

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

Features:

  • A higher shrinkage rate, the greater the probability range for the quilt was diameter containing;
  • Flame retardant, in line with European Union RoSH directive does not contain any halogen, more environmentally friendly, it is to upgrade the existing halogen flame retardant automotive replacement of oil products;
  • Semi-rigid polyolefin material, higher mechanical properties and wear resistance, perform wiring harness connector and terminal stress solution at the excellent abrasion resistance and protection;
  • Thicker layer of hot-melt adhesive, having excellent sealing performance, effectively resist into the immersion fluid and moisture;
  • Excellent oil resistance, especially for use of the car interior environment;
  • Working temperature from -40 ℃ to 135 ℃, suitable for a wider temperature range (starting shrink temperature: 110 ℃, full recovery temperature: 135 ℃).

Applications: This product is designed for automotive wire harness and piping requirements and specific design, can be widely used in a variety of automotive wiring harness insulation seal, stress and other lines and terminals at the local indirect continued release and anti-wear protection properties.
