Note: Models with specifications of Φ30 and above are automatically classified under the G tube category, compliant with the stringent EU RoHS2.0 environmental standards (2011/65/EU).
1. Operating Conditions
1.1 Expertly designed for seamless operation within ambient temperatures stretching from a brisk -55°C to a toasty 125°C.
1.2 Demonstrating unparalleled resilience for enduring performance in aggressive acidic and alkaline environments.
1.3 Constructed to meet and exceed stringent environmental protection mandates.
2. Appearance Requirements
2.1 The surface must exemplify perfection – flawless and devoid of any visible scratches, uneven textures, or bamboo-joint-like marks.
2.2 Expect a surface finish that is impeccably smooth, entirely free from oil stains and dust.
2.3 Guaranteed printing precision with no ghosting, excessive ink, incomplete prints, or slippage, ensuring clarity and legibility.
3. Heat Shrinkage Performance
3.1 Initiating shrinkage at 70°C, the tube achieves full contraction effectively by 125°C.
Aligned with UL224 standards, our tubing reaches a complete shrinkage temperature of 200°C within a swift 3-minute span.
3.2 The longitudinal shrinkage rate is meticulously maintained within a precise ±5% range.
4. Performance Characteristics of Materials
The physical and chemical attributes of our materials are expertly aligned with the stringent criteria outlined in Table 1.
Our halogen-free, flame-retardant, thin-wall heat-shrinkable sleeves conform rigorously to the specifications detailed in Table 2.
The precise dimensions of our halogen-free, flame-retardant heat-shrinkable sleeves adhere stringently to the guidelines set forth in Table 3.
Our dynamic color range includes standard shades of black, red, blue, yellow, green, and white. For bespoke needs, we provide custom options such as purple, gray, and brown, ensuring customer satisfaction.
Embrace the exceptional performance of our premium Single Wall Heat Shrink Tube, meticulously engineered for precision and reliability. Achieving optimal shrinkage is an art that demands careful attention and the right tools. We recommend a forced-air constant-temperature oven, precisely set to the ideal temperature of 125°C. It's crucial to remember that as you introduce the heat-shrinkable sleeve into the oven, the initial temperature may experience a slight dip. Patience becomes your ally, allowing the oven's temperature to stabilize gracefully to the set point. Once the desired temperature is reached, the sleeve will begin its transformation, aided expertly by the oven's circulating hot air. Witness the sleeve reach its full potential as it achieves perfect shrinkage, sustained by maintaining this precise temperature alignment for a robust 3-minute duration.
