Selecting the correct shrink ratio for your application is an important factor when choosing the right heat shrink tubing. Here are some steps to help you determine the appropriate shrink ratio:
- Measure the maximum diameter of the object you want to cover: Measure the widest point of the object you want to cover with the heat shrink tubing, and take note of this measurement.
- Determine the recovered diameter of the tubing: The recovered diameter is the size of the tubing after it has shrunk. You can find this information on the packaging or specification sheet for the heat shrink tubing.
- Calculate the required shrink ratio: The shrink ratio is the ratio of the expanded diameter of the tubing to the recovered diameter. To calculate the required shrink ratio, divide the maximum diameter of the object by the recovered diameter of the tubing.
For example, if the maximum diameter of the object is 50mm and the recovered diameter of the tubing is 25mm, the required shrink ratio would be 2:1.
- Consider other factors: In addition to the required shrink ratio, you should also consider other factors such as the material of the tubing, the temperature range, and the level of protection required.
When selecting heat shrink tubing, it is important to choose a tubing with a shrink ratio that is equal to or greater than the required shrink ratio. Choosing a tubing with a higher shrink ratio can provide better coverage and protection, but it may also require a higher temperature to shrink the tubing properly. Conversely, choosing a tubing with a lower shrink ratio may not provide enough coverage or protection for the object being covered.
Selecting the correct shrink ratio for your application is important to ensure that the heat shrink tubing provides the necessary protection and coverage for the object being covered.
