2:1 Heat Shrink Tubing for Electrical Cable Management
Heat shrink tubeAlso known as heat shrinkable tubing, this product is crafted from cutting-edge polymer materials. Its standout feature is the capability to snugly contract around encased objects upon exposure to heat. At Dongguan Zhonghe Electronics Co., Ltd, we meticulously engineer our heat shrink tubes using premium-grade polyolefin, fluoroplastic, silicone rubber, and polyester. These sophisticated materials lend exceptional, distinct properties to our tubes, enabling them to cater to the diverse and rigorous demands across multiple industries.

Note: Φ30 and above specification products default to G tube, meeting EU RoHS2.0 (2011/65/EU) standard for environmental performance.
1. Operating Conditions
1.1 The ambient temperature for continuous use ranges from -55°C to 125°C.
1.2 Capable of enduring long-term use under both acidic and alkaline conditions.
1.3 Designed to perform reliably under stringent environmental protection requirements.
2. Appearance Requirements
2.1 No obvious scratches, surface irregularities, or bamboo-joint-like defects are present on the product surface.
2.2 The surface is smooth and clean, without oil stains or dust accumulation.
2.3 Printing is precise and clear, free from ghosting, excessive ink, incomplete printing, or slippage.
3. Heat Shrinkage Performance
3.1 Initial shrinkage begins at 70°C, with full shrinkage achieved at 125°C.
In compliance with the UL224 standard, full shrinkage is reached at 200°C within 3 minutes.
3.2 The longitudinal shrinkage rate is maintained within ±5%.
4. Performance Characteristics of Materials
The physical and chemical properties of the materials align with the specifications presented in Table 1.
The dimensions for halogen-free flame-retardant thin-wall heat-shrinkable sleeves adhere to the specifications in Table 2.
The dimensions for halogen-free flame-retardant heat-shrinkable sleeves adhere to the specifications in Table 3.
Available standard colors: black, red, blue, yellow, green, white. Customization is available for other colors like purple, gray, brown, etc., based on customer requirements.
To ensure the heat-shrinkable sleeve achieves optimal shrinkage, it is vital to use a forced-air constant-temperature oven, meticulously maintaining a shrinkage temperature of 125°C. Be aware, as the sleeve enters the oven, the initial temperature may dip, requiring time to stabilize at the desired setting. The sleeve must then reach its final shrinkage temperature through the oven's efficient hot air circulation. Only when the oven's temperature stabilizes and remains at 125°C for approximately 3 minutes will the sleeve fully and optimally shrink into place.
8. Application Field
8.1 Insulation protection for internal wiring within electronics
8.2 Insulation protection for electronics internal wiring
8.3 Ensures waterproof and dust-proof protection for communication cables
8.4 Provides reliable protection for household wire connections
8.5 Versatile materials perfect for DIY jewelry crafting
