Dual-wall with adhesive & multiple shrink ratios, balancing protection and adaptability
2:1, 3:1 and 4:1 colored heat shrink tubing feature an eco-friendly irradiated cross-linked polyolefin outer layer and a hot-melt adhesive inner layer, compliant with RoHS standards and free of harmful substances.
- 2:1 shrink ratio: Suitable for standard cable connectors, shrinks gently without damaging wires.
- 3:1 shrink ratio: Ideal for connectors with medium diameter differences, highly versatile.
- 4:1 shrink ratio: Wide stretching range, perfect for large-diameter diameter-variable parts (e.g., 16 mm shrinks to only 4 mm).
Start shrink temperature: 80 ℃, full shrink temperature: 110 ℃.
When heated, the adhesive layer melts and bonds tightly to various materials, with near-zero water absorption.
It meets V0 flame retardant grade, with an operating temperature range of -55 ℃ to 110 ℃ and dielectric breakdown strength ≥ 20 kV/mm.
Aging-resistant and corrosion-resistant, the colorful design enables circuit classification to avoid misoperation.
- 2:1 version: For household maintenance and light-duty applications.
- 3:1 version: For general industrial construction and automotive wire harnesses.
- 4:1 version: For heavy-duty equipment and large-diameter reducer connectors.
No wrinkles or bubbles after installation.
Tensile and vibration resistant, suitable for exposed installation, concealed installation, outdoor use and direct burial.
Meets the needs of both professional engineering and daily maintenance.
Full-scenario precise matching, protection and identification in one!
- Household maintenance: Choose 2:1 for gentle shrinkage to protect household appliance wires.
- Automotive and photovoltaic fields: Choose 3:1 for versatility and sealing performance.
- Heavy-duty industrial and large-diameter variable diameter scenarios: Choose 4:1 for full stretch to fit complex parts.
Used in building electromechanical wiring: Color classification prevents construction misoperation.
Used outdoors: Weather-resistant and sealed against wind, rain and moisture.
An all-round cable protection accessory for household, commercial and industrial applications.
