Fractional Heat Shrink FEP Tubing 1.6:1 • Mil 23053/11
FEP Heat Shrinkable Tubing is designed to shrink on parts that are greatly uneven in size yet still allowing for a one piece containment. FEP Heat Shrink Tubing with the high shrink ratio of 1.6:1 covers a large range of product sizes but is limited in the smaller diameter parts.
When shrinking FEP tubing generally all that is needed is a heat source that is able to generate 230F. In some situations ovens can be used but you must not put parts directly into a hot oven. Both parts and oven must be brought up to temperature at the same time. This will create a uniform shrink around the part. Convection ovens are also recommended in order to eliminate hot spots which could cause material to shrink unevenly.

How To Shrink FEP
For long wires and tubes start at one end and evenly heat the surface making sure to rotate the part or the heat source so that recovery does not come completely off of one side. Rotating will give you a uniform shrink eliminating air bubbles and keeping the wall even throughout the part. If parts cannot be rotated most heat guns come with a shield or a deflector that can be used in place of rotating. Large metal parts would fare better if they can be pre heated to take the chill off of the part and warm the surface. Over heating the part will cause shrinking to occur prematurely throughout the tube and anywhere the tubing might have come into contact with the hot surface.
Over heating the FEP Tube while shrinking will cause it to crack and become brittle. If this happens the FEP will have a cloudy appearance in spots. Please keep in mind that FEP Heat Shrink Tubing will ACTUALLY sometimes grow in length during shrinking and that material will bunch and wrinkle if it is not allowed to slide and grow over the part.
