    What is PET heat shrink tubing?

    PET tubing definition

    PET heat shrink tubing covers and protects parts in medical devices. PET means polyethylene terephthalate. Manufacturers melt PET pellets. They stretch the material and cool it fast. This locks the shape in place. Radiation is used to cross-link the tubing. This step helps the tubing remember its smaller size. When you heat it, the tubing shrinks tightly around the object.

    Here is a quick look at the main properties of PET heat shrink tubing:

    Property/Metric
