2M Heat Shrinkable Tube PVC Shrink Tubing For Lithium Battery Pack Protection Insulation Casing High Quality Heat Shrink Sleeve

PVC heat shrinkable sleeve has a special function of heat and shrinkage at 105 °C. The products are widely used in various lithium batteries; nickel-hydrogen batteries, nickel-cadmium batteries Mechanical properties of physical products: (1) Appearance: The surface is smooth, the thickness is uniform, no obvious stains, no oil marks, impurities, and folding. (2) Proportion: 1.36. 3) Heat shrinkage: Test at 100 degrees. c, the horizontal shrinkage is 48 ± 3%, vertical 12 ± 3% can be close to the product. The telescopic heat shrink machine can also be used for hair dryers and water shrinking machines. (4) Flexibility: After the package is reduced, it will not break three times on the cement surface in different vertical and horizontal directions of 1 meter high. (5) Color: Blue, after the package is reduced, it will be stored in a 30 degree environment. C has no discoloration, such as discoloration and discoloration. (6) Traction: less than 2%. (7) Rated voltage: 300V; (8) Water absorption rate of 0.5%. (9) Temperature range: -55 ° C ~ 105 ° C; (10) Shrinkage ratio: transverse shrinkage ≥ 48%, longitudinal shrinkage ≤ 8%; (11) × 1015 Ω ≥ 1 resistivity / cm3 (humidity ≤ 65% at room temperature). (12) Electrical performance. Time of pressure breakdown 0.07~0.09≥6KV•Y decDC10 0.10~0.14≥8KV• and decDC10 0.15~0.20≥10KV•Y decDC10 Use the trick: small diameter, short head, you can use a lighter to complete the shrinkage; large diameter or a large number of heat shrinkable tubes, can be used for batch shrinkage treatment with a hot air cylinder / hot air gun; Product features: PVC heat shrinkable sleeve has special function of shrinking when it is hot or shrinking. It can be shrunk when heated above 98°C, and it is easy to use. It has excellent flame retardant, environmental protection, insulation, softness, stable performance, low shrinkage temperature, fast shrinkage, etc. The product has good high temperature resistance and no secondary shrinkage. It can play the role of anti-counterfeiting and beautification of packaging materials, and is packaged. Covered items can be used for insulation, moisture, corrosion, dust prevention, etc. Applications: PVC heat shrinkable sleeves are widely used in electrolytic capacitors, inductors, various rechargeable battery cells, combination packaging, various curtain rods, shower curtain rods, hanging rods, mop rods, broom handles, tool rods, telescopic rods , the outer covering of tubular objects such as garden tools and poles. It can also be used for the identification of copper busbars, joints and wiring harnesses of low-voltage indoor busbars, and insulation coating. High efficiency, low equipment investment, and low overall cost. It is used for lighting, LED pin wrapping, and wrapping of guitar and bottle mouth. Precautions: The actual ruler will have a positive or negative 5% error. Please pay attention when purchasing. Please pay attention to this problem when calculating the size (because each batch comes out, it may be a bit wrong) Choose size: If you don't know the customer who needs a specific size, you need to leave a few more MM space when calculating. A few MMs are certainly hot-shrinking, and they are afraid that they are useless. Please pay attention. Dimensional calculation method (width + height < casing) size. This means that the size of the battery can not exceed the size of the casing. If it is almost the same or just equal to the size of the casing above, it is recommended to use a larger size. If it is large, it can be heated and shrunk. If it is small, it will not be used.) In general, the circumference of the heat shrinkable tube should be > the circumference of the battery.
