Flexible, Thick Adhesive Lined Dual Wall Heat Shrinkable Tube is manufactured by co-extrusion of polyolefin and hot-melt adhesive. Designed to provide both insulation and sealing for protected articles. Used to protect bundles wires and metal tubes against water and moisture.
Features:
- Flexible, thick adhesive lined to bond to a wide variety of plastics, rubber and metals
- Operating Temperature: -45℃～125℃
- Shrinking Temperature: Start at 70℃, and shrunk totally at 125℃
- Shrink Ratio: 3:1
Polyolefin Heat Shrink Sleeve, 3:1 - SBRS-(3X) GLW
