Does all heat shrink tubing shrink the same amount?

- Sep 14, 2018-

Each type of heat shrink on the market is labeled with a shrink ratio, or the measurement of how small the tubing becomes when shrunken in comparison to its original expanded size. For example, heat shrink tubing with a 2:1 shrink ratio has an expanded diameter that is twice the size of its shrunken diameter. Likewise, a 6:1 ratio indicates that a piece of heat shrink is capable of shrinking to 1/6th of its expanded size. These, of course, aren't the only shrink ratios out there; a wide variety is available on the market, but their ratios can all be interpreted as easily as the two examples just given.
