Descriptionis_customized : YesMaterial : PVCModel Number : heat shrink tubing Shrink tubeType : Heat ShrinkableCertification : NONEOrigin : Mainland China1kg PVC heat shrink tubing Shrink tube a variety of specifications 18650 battery shrink sleeve Insulation casing Heat shrinkFeatures and specifications:Product physical mechanical properties: Appearance: Smooth surface, uniform thickness, no obvious spots, no traces of oil, impurities, folding Proportion: 1.36 Heat shrinkage: Tested at 100C, horizontal shrinkage of 48 3%, vertical 12 3% can be close to the product Shrinkable heat shrinkable machine can also be used hair dryer, water shrinkage Flexibility: After the package shrinks, it will not crack on cement surface three times in different directions from vertical and horizontal from 1 meter height. Color: After the package shrinks, it will be stored in the environment of 30C without color change such as discoloration and discoloration. Tensile: Less than 2%. Water absorption: 0.5% Natural Shrinkage: 0.5% at 30C Resistivity: 1 1015 / cm3 (relative humidity 65% at room temperature). Electrical performance Single-layer thickness breakdown voltage breakdown time 0.07 ~ 0.09 6KV & decDC10 0.10 ~ 0.148KV & decDC10 0.15 ~ 0.2010KV & decDC10Product scope and industry:1) Widely used in all kinds of commodities such as wine, food, sporting goods, disinfecting tableware, electric appliance, daily necessities, handicrafts, building materials, audio and video products, medicines, stationery, toys, portals, plastic hardware, glass ceramics, packaging, and so on2) Appearance is clear and beautiful, improves product packaging grade, protects from dust, flowers and other protective effect is the ideal film packaging material3) Bottle packaging: Food and medicine bottle anti-corrosion, anti-leak sealing, such as: cosmetics nozzle, soy sauce bottle, wine bottle mouth, glass bottles and plastic bottle mouth packaging, gas bottle switch package, five gallons of mineral water bottle Packaging and so on4) Insulating packaging for electrolysis fuses, batteries, lighting, inductors, metal steel pipes, wire and cable joints, etc., with the features of anti-corrosion, dustproof, acid/alkali-proof, colorful, smooth surface, low price and good insulation propertiesShowcaseSizeHow to choose the size you need:1) First of all, our size is the width of the heat shrinkable tube, so the heat shrinkable tube has a circumference that is twice the size.2) Calculate the perimeter of the battery pack. Generally, the circumference of the heat shrinkable tube should be > the circumference of the battery pack.
