10m PVC Heat Shrink Tube 17-500mm 18650 Lithium Li-ion Battery Heatshrink Tubing

• 10 Metres.
• 10m PVC Heat Shrink Tube 17-500mm 18650 Lithium Li-ion Battery Heatshrink Tubing.
• Size: 1m*30mm / 39*1.18in,1m*50mm / 39*1.97in,1m*65mm / 39*2.56in,1m*75mm / 39*2.95in,1m*85mm / 39*3.35in.
• Product colour: blue.
• Applications: battery pack, rope covering, pool hose covering etc.
• PVC heat shrink is much thinner than polyolefin heatshrink.
• Smooth surface, uniform thickness, no obvious spots, no traces of oil, impurities or creasing (other than the flatended edge with is removed in the shrinking process).
• We also stock blue, black, green and clear in lengths from 0.5m to 20m.

How to choose the size

• The measurements you are choosing above are the flat widths of the heat shrink. Easy calculations are below. Alternatively, please view the table below.
• If you are sliding the heatshrink over the end of a rectangular object, the quick way to calculate the flat width required is to simply add the height and width and add a small percentage to ensure it fits over. That's because the flat width is the circumference (perimeter) divided by two plus a small extra percentage such as 10-20% to make sure it goes over. Flat width = 2(L+W)/2, which equals LW.
• If you are sliding the heatshrink over the end of a circlular object you can either measure the diameter, radius or circumference of the object. If you measure the circumference, divide by two and then add a small percentage. If your object is 200mm circumference you need a flat width of 120mm approximately (20% more than half). Use a string to span the circumference and then measure the string that went around. 
• Whatever the shape of the object, run a string around it, measure the length of the string, divide by 2 and then add a small percentage.
• If you want to convert the other way i.e. flat width to round width, then multiply flat width by 2/pi.
• You can use much larger heat shrink because of the large shrinkage ratio of PVC heat shrink. Slowly apply heat due to the low melting temperature of PVC. Even a hair dryer of reasonable quality is hot enough.
