Waterproof thermofit heat shrink tube with glue

Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Insulation & Sealing: Designed to provide waterproof protection and thermal insulation for low-voltage electrical connections, using a polyethylene (PE) material with integrated glue lining to ensure a secure, moisture-resistant seal.
  • Adaptive Shrink Technology: 3:1 shrink ratio allows the tube to uniformly contract over cables or joints, adapting to varying diameters while maintaining structural integrity under 1kV rated voltage.

Key features

  • 1. Waterproof PE Material with Adhesive Lining

    • With waterproof polyethylene (PE) material and integrated thermofit adhesive, ensure secure sealing against moisture, corrosion, and environmental damage. Disclaimer: Based on internal testing; actual results may vary.

  • 2. RoHS, EU 2015/863, and UL Certifications

    • With compliance to RoHS, EU 2015/863, and UL standards, meet strict safety and environmental regulations for global industrial and commercial applications.

  • 3. 3:1 Shrink Ratio for Versatile Insulation

    • With a 3:1 shrink ratio, effectively conform to irregular shapes and tight spaces, offering 50% better shape adaptation than standard 2:1 shrink tubes*. Disclaimer: Based on comparative testing; results may vary by application.

  • 4. 1kV Rated Voltage for Safe Low-Voltage Use

    • Rated for 1kV, safely insulate low-voltage wiring while outperforming non-rated alternatives in voltage tolerance and durability.

  • 5. Harsh-Environment Durability

    • Designed for outdoor and industrial use, withstand extreme temperatures and corrosive conditions to ensure continuous operation in demanding scenarios.

Supplier's note

  1. Key Breakthroughs:

    • 3:1 Shrink Ratio: Outperforms traditional 2:1 benchmarks, enabling tighter seals in compact spaces.
    • 180°C Temperature Tolerance (Pro): Enables use in high-heat industrial machinery.
    • Premium Chemical Resistance (Pro): Safely handles aggressive fluids like solvents or corrosives.

  2. Version Selection Guide:

    • Base Model: Suitable for standard low-voltage applications (e.g., consumer electronics, basic wiring).
    • Advanced Model: Ideal for automotive or HVAC systems requiring oil/acid resistance.
    • Pro Model: Best for industrial equipment in extreme environments (e.g., chemical plants, heavy machinery). With the Pro’s tripled chemical resistance, users can safely handle corrosive fluids while its 5:1 shrink ratio ensures secure fits in tight spaces. Pair with its high-temperature rating to maintain integrity in engine compartments or boilers.
