Note: Φ30 and above specification products default to G tube, aligning with EU RoHS2.0 (2011/65/EU standard) for superior environmental compliance.
1. Operating Conditions: Ensuring consistent performance across varied environments.
1.1 The ambient temperature: Ranges from a frosty -55°C to a scorching 125°C, allowing for robust, continuous use.
1.2 Resistant to long-term exposure under both acidic and alkaline conditions, showcasing durability and reliability.
1.3 Designed for prolonged use under stringent environmental protection standards, ensuring sustainability.
2. Appearance Requirements: Aesthetic perfection meets industrial functionality.
2.1 Flawless surface with no visible scratches, unevenness, or bamboo-joint-like defects, ensuring high-quality presentation.
2.2 A smooth surface free from oil stains and dust, maintaining pristine condition.
2.3 Crisp and clear printing, devoid of ghosting, excess ink, incomplete printing, or slippage.
3. Heat Shrinkage Performance: Unveiling the strength of adaptability.
3.1 Initial shrinkage begins at 70°C with full shrinkage achieved at 125°C, ensuring a snug and protective fit.
According to UL224 standards, full shrinkage is accomplished at 200°C within 3 minutes, offering quick and efficient application.
3.2 The longitudinal shrinkage rate remains within a precise ±5% range, ensuring dimensional stability.
4. Performance Characteristics of Materials: Unmatched quality and durability.
The physical and chemical properties of the materials adhere to the superior standards outlined in Table 1, ensuring exceptional performance.
5. Product Dimensions: Precision-tailored dimensions for exceptional application.
The dimensions of halogen-free flame-retardant thin-wall heat-shrinkable sleeves are meticulously aligned with the specifications in Table 2, ensuring a precise fit.
The dimensions of halogen-free flame-retardant heat-shrinkable sleeves meet the stipulated standards in Table 3, guaranteeing reliable application.
6. Colors: A spectrum of choices for tailored customization.
Standard colors include black, red, blue, yellow, green, and white, with bespoke options like purple, gray, and brown available to meet specific customer preferences.
7. Usage Method: Efficient and intuitive handling for diverse applications.
To maximize the efficiency and ensure a perfect fit when using the heat-shrinkable sleeve, it is crucial to deploy a forced-air constant-temperature oven with precision. The optimal shrinkage temperature is meticulously set at 125°C. Be mindful that upon placing the sleeve into the oven, a slight temperature dip may occur, requiring a brief period for stabilization to the set temperature. Additionally, the sleeve itself needs adequate time for the heat to circulate fully and achieve its optimal shrinkage. Only when the oven's actual temperature aligns with the designated setting and remains consistent for approximately 3 minutes will the sleeve fully contract to its intended form.
