High-Quality PVC Heat Shrink Tube for 18650 Battery - 1M/3.28Ft Length, 85mm Flat Width, Black | Electrical Insulation, Wire Protection & DIY Projects

PVC heat-shrinkable tubes are widely used in electrolytic capacitors, inductors, various rechargeable batteries, combination bags, various curtain rods, shower curtain rods, hanging rods, mop rods, brooms, tool rods, telescopic rods, shells of tubular items and other gardening tools and gaskets.feature:Material: PVCColour: BlackPackage Included :1 x PVC Shrink Wrap TubePrecaution:1. Diameter calculation: diameter = flattened width X2/3.14 = flattened width and other circular inner diameterDiameter of 90mm shrink wrap = 90 X 2/3.14 = 57.2mmFor example: the maximum outer diameter of your product is 57 mm X 3.14 / 2 = 89.5 so your width is 90 mmyou can take it. I recommend buying a bigger one.2. Calculation of perimeter: perimeter/2 = flattened width! If it is a rectangular object, width + height = flattened flattened width! (note that you have to keep larger points to fit)If you still don't know which width to buy. You can wrap the product in a circle with white paper, (paper width / 2 = flattened width)3. Note: Please reserve a bit wider when purchasing, otherwise it will not fit!

Material: Made of high quality heat shrinkable PVC, temperature range: -55°C~105°C;

Good insulation: soft and stable performance, rapid shrinkage shrinkage rate: 8%;

Advantages: PVC heat shrink tubing is a thin-walled, low-cost material with good electrical and mechanical properties. When exposed to excessive heat for a few seconds, the specially formulated PVC material shrinks rapidly and conforms to the shape of the object being coated evenly.

Applicable scene: suitable for insulation and sheathing of batteries, capacitors, etc. In addition, it has a wide range of applications in the production of industrial equipment, toys, sporting goods, electronics and consumer goods.

Note: Please keep the PVC heat shrinkable tube in a cool place to avoid high temperature deformation.
