Note: Specifications for sizes Φ30 and above are standardized to the G tube model, aligning with EU RoHS2.0 environmental performance standards (2011/65/EU).
1. Operating Conditions
1.1 Engineered for continuous operation, enduring ambient temperatures from a frosty -55°C to a toasty 125°C.
1.2 Demonstrates outstanding resilience in long-term use, even within challenging acidic and alkaline environments.
1.3 Designed to meet stringent environmental protection requirements, ensuring sustainability and safety.
2. Appearance Requirements
2.1 The surface of the tubing must remain pristine, devoid of any visible scratches, uneven textures, or bamboo-joint-like imperfections.
2.2 The exterior finish must be flawlessly smooth, ensuring zero oil stains and absolutely no dust accumulation.
2.3 Printing quality is paramount, with no ghosting, excess ink, incomplete prints, or slippage tolerated.
3. Heat Shrinkage Performance
3.1 Initiation of shrinkage occurs at 70°C, achieving complete contraction at 125°C.
In line with UL224 standards, the tubing reaches its full shrinkage temperature of 200°C within a mere 3 minutes.
3.2 The longitudinal shrinkage rate is meticulously maintained within a precise ±5% margin.
4. Performance Characteristics of Materials
The physical and chemical properties of the materials are carefully aligned with the stringent criteria detailed in Table 1.
The measurements of our halogen-free, flame-retardant, thin-wall heat-shrinkable sleeves are rigorously designed to comply with the specifications set out in Table 2.
The dimensions of our halogen-free, flame-retardant heat-shrinkable sleeves are meticulously crafted to follow the exacting guidelines in Table 3.
Our standard color palette includes classic shades such as black, red, blue, yellow, green, and white. We also offer custom color options like purple, gray, and brown to fulfill specific customer preferences.
Experience the unparalleled quality of our top-tier Single Wall Heat Shrink Tube, meticulously engineered for exceptional performance. Achieving optimal shrinkage is an art that demands precision. For best results, utilize a forced-air constant-temperature oven, precisely adjusting the shrinkage temperature to a perfect 125°C. It's crucial to understand that once the heat-shrinkable sleeve is placed inside, the oven's initial temperature might slightly decrease. Patience is your ally as the oven methodically stabilizes to the designated heat. In this phase, the sleeve begins its transformative journey toward its ideal shrinkage, expertly supported by the oven's circulating hot air. The sleeve reaches its full potential when the oven's actual temperature matches the set target, maintaining this synergy for a steadfast 3-minute interval.
