2:1 Heat Shrink Tubing for Electrical Cable Management
Heat shrink tube, also known as heat shrinkable tubing, is crafted from cutting-edge polymer materials. Revel in its remarkable ability to seamlessly contract and embrace the encased object upon exposure to heat. At Dongguan Zhonghe Electronics Co., Ltd, we pride ourselves on manufacturing these tubes with extraordinary precision, utilizing premier polyolefin, fluoroplastic, silicone rubber, and polyester. These materials bestow exceptional qualities on our products, ensuring they fulfill the varied and stringent requirements of multiple industries.

Note: Products with specifications of Φ30 and above are defaulted to G tube (compliant with EU RoHS2.0 (2011/65/EU) standards for environmental performance).
1. Operating Conditions
1.1 The ambient temperature for continuous use: -55°C to 125°C.
1.2 Suitable for prolonged use under both acidic and alkaline conditions.
1.3 Ideal for extended use where strict environmental protection is paramount.
2. Appearance Requirements
2.1 The product's surface is free from any prominent scratches, unevenness, or bamboo-joint-like defects.
2.2 The surface is impeccably smooth, devoid of oil stains and dust accumulation.
2.3 Print quality is crisp and clear, without any ghosting, excess ink, incomplete areas, or slippage.
3. Heat Shrinkage Performance
3.1 The initial shrinkage temperature is 70°C; achieves full shrinkage at 125°C.
Compliant with UL224 standards, the full-shrinkage temperature is 200°C for 3 minutes.
3.2 The longitudinal shrinkage rate remains within ±5%.
4. Performance Characteristics of Materials
The physical and chemical properties of our materials are aligned with the specifications in Table 1.
The dimensions of our halogen-free flame-retardant thin-wall heat-shrinkable sleeves adhere to the standards demonstrated in Table 2.
The dimensions of our halogen-free flame-retardant heat-shrinkable sleeves comply with the regulations set forth in Table 3.
Our standard color palette includes black, red, blue, yellow, green, and white. Additionally, customization options are available for colors such as purple, gray, brown, and more, tailored to customer requirements.
To ensure that our premium 2:1 Single Wall Heat Shrink Tube Roll achieves its full potential during use, it's essential to utilize a forced-air constant-temperature oven. Maintain a controlled shrinkage temperature at a precise 125°C. Be mindful: once the heat-shrinkable sleeve enters the oven, initial temperature dips may occur, requiring time to stabilize at the desired setting. Additionally, allow time for the sleeve to reach its optimal shrinkage temperature through the oven's hot air circulation. Achieve perfect shrink results by ensuring the oven sustains the set temperature for approximately 3 minutes, guaranteeing a flawless finish.
8. Application Field
8.1 Exquisite insulation protection for electronics internal wiring
8.2 Insulation protection for electronics internal wiring
8.3 Reliable waterproof and dust-proof solutions for communication cables
8.4 Robust protection for household wire connections
8.5 Versatile materials for DIY jewelry creation
