1. Operating Conditions
1.1 Expertly designed for continuous operational efficiency within ambient temperatures ranging from a frigid -55°C to a comfortable 125°C.
1.2 Demonstrates remarkable durability for enduring long-term use in both stringent acidic and alkaline environments.
1.3 Constructed to meet demanding environmental protection standards, ensuring sustainable use.
2. Appearance Requirements
2.1 The surface is required to be pristine, devoid of any visible scratches, uneven textures, or bamboo-joint-like marks, ensuring a flawless finish.
2.2 The exterior finish must be impeccably smooth, devoid of oil stains and absolutely free from dust accumulation.
2.3 Printing excellence is assured, guaranteeing no ghosting effects, excess ink, incomplete prints, or print slippage.
3. Heat Shrinkage Performance
3.1 Shrinkage initiates at 70°C, achieving complete contraction at 125°C, ensuring optimal performance.
In alignment with UL224 standards, full shrinkage is accomplished at a temperature of 200°C within a mere 3 minutes.
3.2 The longitudinal shrinkage rate is precisely controlled, maintained within an exacting ±5%.
4. Performance Characteristics of Materials
The material's physical and chemical properties are meticulously aligned with the stringent criteria detailed in Table 1, ensuring top-notch reliability.
The dimensions of our halogen-free, flame-retardant, thin-wall heat-shrinkable sleeves adhere rigorously to the specifications outlined in Table 2.
The dimensions of our halogen-free, flame-retardant heat-shrinkable sleeves follow the precise guidelines detailed in Table 3.
Our standard color palette includes black, red, blue, yellow, green, and white. We also offer custom color options such as purple, gray, and brown to meet specific customer preferences and requirements.
When engaging with our top-tier Single Wall Heat Shrink Tube, meticulously engineered for unparalleled performance, achieving the perfect shrinkage requires careful attention to detail. For optimal results, we recommend utilizing a forced-air constant-temperature oven, precisely setting the shrinkage temperature to a precise 125°C. It's crucial to be aware that upon inserting the heat-shrinkable sleeve into the oven, the initial temperature may momentarily decrease. Exercising patience is essential, as the oven gradually stabilizes, reaching the desired temperature setting. Subsequently, the sleeve will need time to reach its ultimate shrinkage temperature, expertly facilitated by the circulating hot air within the oven. The sleeve achieves its maximum shrinkage potential when the oven's actual temperature aligns perfectly with the set point, maintaining this alignment for a consistent 3-minute duration.
8. Application Field
8.1 Providing robust insulation protection for the complex internal wiring of sophisticated electronics
8.2 Insulation protection for electronics internal wiring
8.3 Ensuring that communication cables remain both waterproof and dust-proof
8.4 Delivering reliable protection for household wire connections
