How Do I Know When I Can Use PTFE Shrink Tubing?

To determine whether you can use PTFE shrink tubing, you will need to know the tolerance temperatures of the materials, which you are placing the tubing around. This type of shrink tubing has to be heated to around 650 degrees Fahrenheit in order for it to start shrinking. You should experiment with a test piece of tubing and the material, to determine whether the material will still be viable after shrinking.


PTFE Shrink Tubing Works with Most Types of Metals


Most types of wiring and cable are designed to withstand high temperatures, which allow it to be used with PTFE shrink tubing. Copper, stainless steel, carbon steel, aluminum and titanium have melting points well beyond the temperature range required to shrink this type of tubing. When working with a particular type of metal and this type of shrink tubing, you will want to check the melting point of the metal, before applying the tubing.
