High Viscosity Adhesive-Lined Polyolefin Heat Shrink Tubing
Basic Info
Basic Info.
4:1 shrink ratio allows for fewer sizes to cover numerous splice configurations and diameters.
Thick adhesive liner forms an effective barrier against fluids and moisture penetration.
Minimum shrink temperature: 70°C .
Continuous operating temperature: -45°C to 125°C .
Fully shrink temperature:125℃.
Standard color: black , clear (other colors can be customized).
Application:
Sealing waterproof, anti-corrosion, leakproof, multi-strand wire harness and insulation
Wire harness
Marine wire and cable
Metal pipe need to seal waterproof, moisture-proof, anti-corrosion sealing insulation, binding fixed
