New Energy Heat Shrink Tubing

As a manufacturer and supplier of New Energy Heat Shrink Tubing, Lijingda Hardware is committed to providing innovative solutions to meet the electrical connection needs of new energy vehicles. Our tubing utilizes high-quality materials and advanced techniques to ensure its reliability and stability under high temperatures, pressures, and harsh environments.

Manufacturing process

Our company prioritizes professional technology and production personnel. We extrude thermoplastic polyolefin material into a molded tube, then coat the inner surface with a layer of copper foil. Heat shrinking technology cleverly bonds the copper foil to the tube wall. This process creates a close contact between the tube wall and the copper foil, ensuring unimpeded electrical flow and a stable electrical connection. Finally, our New Energy Heat Shrink Tubing undergo rigorous quality inspections to ensure compliance with electrical standards and safety requirements.

Performance Characteristics

1) Conductive Performance: New Energy Heat Shrink Tubing utilizes copper foil as the conductive material, exhibiting excellent conductivity to ensure stable current transmission.

2) Heat Shrink Performance: The tubing demonstrates outstanding heat shrink properties, rapidly contracting to the desired diameter when heated, tightly enveloping the connection area to create a secure sealing effect.

3) Tensile Strength: It boasts good tensile strength, maintaining connection stability even under mechanical vibrations or external forces, thereby reducing the risk of failure due to external influences.

4) High-Temperature Resistance: This product maintains stable performance even in high-temperature environments, remaining unaffected by temperature fluctuations to ensure safe and stable electrical connections.

5) Corrosion Resistance: The copper foil material offers excellent corrosion resistance, capable of resisting the erosion of various chemical substances on the connection area, thereby extending the product's lifespan.

FAQ

What is the typical shrinkage temperature?

To ensure no rebound or performance degradation occurs under high-temperature operating conditions, New Energy Heat Shrink Tubing has a fully contracted temperature range of approximately 110℃ - 130℃, while operating at around 70℃ - 90℃.

How can you determine if it has fully contracted?

When the surface of the heat shrink tube becomes smooth, shiny, and tightly adheres to the protected object, and no longer shrinks with heating.

Which major industry standards does it comply with?

It complies with relevant vehicle-grade standards such as UL 224 (Electrical Insulation Tube Standard), SAE AS23053 (Insulation Tube Standard), and ISO 16750 (Environmental Conditions for Road Vehicles Electrical and Electronic Equipment).
