Although heat shrinkable tubes are widely used in life, there are still many friends who do not know enough about the use and selection of heat shrinkable tubes. In the following content, we will introduce to you several aspects that need to be considered in the purchase of heat shrinkable tubes.
Details as follows:
First, we should consider how to choose a heat shrink tube size: choosing the right heat shrink tube size requires taking the correct measurements yourself. Using a vernier caliper or a ruler, you want to measure the diameter of the smallest and largest part. Choose heat shrink tubing that is twenty to thirty percent larger than your largest measurement. An additional 20 to 30 percent will allow room for the expanded tube to slide over the largest section. Don't forget your small metering to make sure the heat shrink tubing has a high enough shrinkage to get a tight fit with the smallest part you want to cover. Lastly, buy a little extra when you order, because some heat shrink tubing shrinks lengthwise too! This measurement method is called the "longitudinal shrinkage" specification.
What are some important indicators to consider when choosing heat shrink tubing: the maximum diameter of the object to be heat shrinked and the temperature range are two important factors to consider when you choose heat shrink tubing. Because these products vary widely in size, thermal shrinkage is also an important indicator to consider. And because the shrinkage of the heat shrinkable tube requires external heating, the temperature resistance of the heat shrinkable object is also an important indicator to consider.
