1M 29-330mm Transparent Heat Shrink Battery PVC Tube Heatshrink

• 1 metre (size displayed on image).
• 1M Clear PVC Heat Shrink Tubing 29-164mm Transparent Battery PVC Heat Shrinkable Tube Heatshrink.
• Note: The "325mm creased" option is heavily folded similar to a double fold. It may make it more difficult to shrink in this region, hence the cheaper price. We will not pay for any return that relates to not knowing about this prior to purchase.
• Note: We also stock other colours of heatshrink, including blue from 30mm to 500mm flat width. We also have orange, red, green, white and yellow.
• 29-325mm FLAT WIDTH (see how to convert below for diameter or a rectangular/square shape).
  
• Applications: battery pack.
• PVC heat shrink is thinner than polyolefin heatshrink.
• Sizes available: choose 29/70/75/96/135/145/164/200/250/325mm.
• Colour: Transparent / Clear.
  
• Environmental friendly, insulation, soft and stable performance.
• Low shrinkage temperature, fast contraction.
• Application: Used to cover large battery holders or packs, especially lithium batteries.

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.

* remember to add a small percentage to the Exact Flat Width's below.
