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.
