How To Shrink Guide- FEP Tex-Shrinkable Tubing |
| |
| TexLoc FEP heat shrinkable fluoropolymer tubing is a high quality tube that has been expanded mechanically to slide over a part and is then heated to shrink down to a tight fit that will not fall off. | It can be manufactured in a variety of shrink ratios depending on the type of material. FEP
heat shrink will grow in length during the shrink process. | On long objects, excess growth may cause wrinkles unless the FEP
heat shrink is allowed to slide forward over the object.

Installation
|
- Read all instructions first.
- Large objects or solid rods must be pre-heated to get a
uniform shrink on the length of the large object being overheated.
- If you have a long cable or tube to shrink over, start
at one end and rotate while applying heat. This will give a uniform
shrink with no air bubbles between the shrink tubing and the rod or cable.
- Heat uniformly around the shrink tubing until the
tubing begins to shrink. Avoid overheating the FEP shrink tubing or
it will become brittle and have a cloudy look. Before this happens, it
will become crystal clear and melt and never recover fully.
- Remove the heat source.
Allow the shrink tubing to cool slowly. Rapid quenching in water may
freeze the material and prevent complete recovery.
CAUTION: If the
tubing cracks, you have probably over heated the material.
