​​Dual Wall Heat Shrink Tubing

IP68 waterproof heat shrink with -45°C~125°C range. Solves corrosion in marine cables & EV batteries. UL/RoHS certified. 10+ colors. Custom printing. Free moisture test kit.

Main Parameter

  • Durability: High tensile strength (≥10.4 MPa) and elongation (≥200%) ensure long-term cable protection.
  • Heat Resistance: Withstands aging at 158°C for 168 hours while retaining mechanical properties.
  • Safety Compliance: Passes flame retardancy (ASTM D 2671) and electrical insulation tests (IEC 60243/60093).
  • Adhesive Reliability: Hot-melt glue offers strong bonding (≥120N/25mm on PE) and low water absorption (<0.2%).
