1. Operating Conditions
1.1 Engineered for continuous functionality in ambient temperatures from a brisk -55°C to a cozy 125°C.
1.2 Demonstrates outstanding durability for long-term operation in challenging acidic and alkaline environments.
1.3 Constructed to meet rigorous environmental protection standards.
2. Appearance Requirements
2.1 The surface must be pristine, devoid of visible scratches, unevenness, or bamboo-like marks.
2.2 The exterior finish should be flawlessly smooth, free from oil stains and dust accumulation.
2.3 Ensures impeccable printing quality with no ghosting, excess ink, incomplete prints, or slippage.
3. Heat Shrinkage Performance
3.1 Initial shrinkage occurs at 70°C, with complete contraction achieved at 125°C.
Compliant with UL224 standards, the full shrinkage temperature of 200°C is attained within 3 minutes.
3.2 The longitudinal shrinkage rate is meticulously maintained within ±5%.
4. Performance Characteristics of Materials
The physical and chemical properties of the materials are precisely aligned with the criteria set forth in Table 1.
The dimensions of the halogen-free, flame-retardant, thin-wall heat-shrinkable sleeves are stringently as per the specifications in Table 2.
The dimensions of the halogen-free, flame-retardant heat-shrinkable sleeves are precisely as per the guidelines in Table 3.
Our standard palette features black, red, blue, yellow, green, and white. We also offer bespoke color selections like purple, gray, and brown to cater to customer-specific preferences.
Experience the exceptional performance of our premium Single Wall Heat Shrink Tube, meticulously crafted to meet all your high-performance needs. To ensure perfect shrinkage, use a forced-air constant-temperature oven, precisely setting the shrinkage temperature to 125°C. It's crucial to remember that placing the heat-shrinkable sleeve into the oven may initially cause a slight dip in temperature. Exercise patience as the oven gradually stabilizes to the desired thermal level. As the oven reaches the specified temperature, the sleeve will progressively adjust to its ultimate shrinkage temperature, expertly assisted by the circulating hot air within the oven. When the oven's operational temperature matches the preset level and maintains this harmony for an uninterrupted 3-minute period, the sleeve achieves its full shrinkage potential, showcasing our commitment to excellence.
8. Application Field
8.1 Providing insulation protection for the intricate internal wiring of electronics, ensuring reliability and safety.
8.2 Insulation protection for electronics internal wiring, safeguarding against potential hazards.
8.3 Guarantee that communication cables remain waterproof and dust-proof, maintaining seamless connectivity.
8.4 Offer reliable protection for household wire connections, enhancing the longevity and functionality of your home systems.
8.5 Versatile materials perfectly suited for DIY jewelry making, enabling creative expression with reliability.
