Double-walled colored adhesive triple-thick heat shrinkable tube
Product specification:01.6mm-050mm
Contraction temperature: Initial contraction temperature: 70-80°C, complete contraction temperature:125°C
Temperature range: -55°C ~125 °C
Product color: black, white, transparent, red, yellow, blue, green, etc
Features: 3:1 high shrinkage ratio, sealing protection, strain buffer
Use tips: lt is recommended to use a heat gun, hair dryer or lighter to heat contraction
Structural Layers:
Inner Layer: Flexible insulating material providing high dielectric strength, ensuring insulation performance at cable joints.
Middle Layer: Polyethylene (PE) material acting as the primary insulation layer, withstanding the main voltage stress.
Outer Layer: Semi-conductive material providing electrical shielding, uniform electric field distribution, and eliminating interfacial air gaps.
Core Advantages: This three-layer structure fuses into a tight, void-free, monolithic piece after shrinkage, integrating the triple functions of stress control, insulation shielding, and mechanical protection.
| Performance Dimension | Key Indicators/Parameters | Technical Advantages & Description |
|---|---|---|
| Physical & Mechanical |
Shrink Ratio: 3:1; Shrink Temp: 80℃~120℃; Tensile Strength: >10.4Mpa; Elongation at Break: >300% |
High shrink ratio accommodates irregular shapes; wide shrink range allows for easy installation; high elongation ensures toughness and resistance to mechanical damage after installation. |
| Thermal & Weather Resistance |
Operating Temp: -45℃~125℃; Heat Shock (250℃/4hrs): No cracking, no dripping |
Suitable for extreme temperature variations, from harsh outdoor cold to high-temperature engine compartments. Maintains stable performance and resists aging. |
| Electrical Properties |
Voltage Rating: 600V; Volume Resistivity: >10^14Ω.cm |
Excellent electrical insulation, effectively protecting circuits and preventing leakage or short circuits. |
| Sealing & Environmental |
Water Absorption: <0.5%; Flammability Rating: VW-1; Environmental Compliance: RoHS compliant |
Low water absorption means superior waterproof sealing; VW-1 flammability rating helps prevent fire propagation; RoHS compliance ensures safety and environmental friendliness. |
Strong R&D and Customization Capabilities
We have a professional team with years of experience in heat shrink material formulation and process development. We understand that different industries (e.g., automotive wiring, electronics, shipbuilding, power/telecom) have unique requirements. Therefore, beyond standard sizes (e.g., Φ3/1 to Φ50/19), we can customize special dimensions, colors (red, blue, yellow, white, clear, etc.), and specific properties (such as halogen-free, oil-resistant) based on customer needs.
Advanced Manufacturing & Irradiation Equipment
Our factory is equipped with multiple high-energy electron beam accelerators, the core technology ensuring the "memory effect" of our heat shrinkable products. We operate fully automated production lines from extrusion, expansion, and rewinding, ensuring precise control from raw material to finished product.
