Teflon® heat shrink tubing may be identified by its chemical name or abbreviation since Teflon® is a brand name. You might see this type of tubing listed as PTFE or polytertafluoroethylene heat shrink tubing. Regardless of how the tubing is identified it functions and preforms the same. Any time the right amount of heat is applied to the correct size tubing it will shrink and create a firm fitting over various kinds of materials.
Make Sure to Select the Correct Shrink Ratio When Using Teflon® Heat Shrink Tubing
There are several different heat shrink ratios available with Teflon® heat shrink tubing. The heat ratios refer to the amount of shrinkage the tubing will provide after heat has been applied based on the starting size of the tubing. It is important to understand the differences between the ratios in order to select the right type of tubing for your applications. For example, a ratio of 2:1 means the tubing shrinks to about half of the starting size.
