What To Pay Attention To When Purchasing The Heat Shrink Tubing
- Aug 13, 2018 -

Heat-shrink tubing is now widely used in life, but many friends still don't know how to choose a heat-shrinkable sleeve. Here are some of the aspects that need to be considered in the purchase of heat shrink tubing.

The following three points should be noted when selecting a heat shrinkable sleeve:

1. Consider how to choose a heat shrink tube size

It is best to take the right measurements by choosing the right heat shrink tubing size. It is usually measured with a vernier caliper or a ruler. The minimum and maximum diameter of the sleeve is measured. Choosing a heat-shrinkable tube is 20 to 30 percent larger than the maximum measured value of the object you are measuring. At the same time, a small metering is taken into account to ensure that the heat-shrinkable tube has a sufficiently high shrinkage ratio to ensure that the sleeve is in close contact with the object. Finally, when you place an order, buy a little extra, because some heat shrink tubings also shrink longitudinally! This measurement method is called the "longitudinal contraction" specification.

2. Consider some important indicators

The maximum diameter and temperature range of the heat-shrinkable object are two important factors to consider when choosing a heat-shrinkable tube. Because the size of these products varies greatly, heat shrinkage is also an important indicator to consider. Because the shrinkage of the heat-shrinkable tube requires external heating, the temperature resistance of the heat-shrinkable object is also an important indicator for consideration.

3. Consider how to choose the heat shrink tubing color

Color we generally choose black, because the application of double wall tube is still bad, other colors are not necessary, and the special color, the manufacturer will charge a special processing fee, and the addition of the masterbatch inside will also increase the cost, so it is more expensive, But these are all due to customers.
