Halar Braided Sleeving


What is Halar® braided sleeving?

Expandable braided sleeving is very similar to those "Chinese Finger Cuffs" that we've all gotten our fingers stuck in.. When you push the end back, the sleeving expands to go over wires easily, and then when you let go, the sleeving comes back to its original diameter (or the diameter of your wire harness or bundle, whichever is larger).

Ethylene-Chlorotrifluoroethylene (E-CTFE) is sold under the tradename Halar. It is a highly chemical resistant material with excellent thermal stability, high moisture resistance, and very low outgassing. Because of its low smoke generation during a fire, it has been found suitable for plenum applications. Halar has also been approved by NASA for use in the space program due to its low outgassing.

Halar Braided Sleeving is used in aerospace, military, fiber optic, and construction applications because of its high fire retradancy, low smoke generation, and low outgassing properties. Halar is a very cost effective alternative to Teflon because of these properties, and its high temperature resistance.

How can I get a fray resistant braided sleeve?

There are limited choices for fray resistant Halar braided sleeves on the market. One particular type has a resin applied to the braid causing the individual filaments to stick to each other. This product is sold in the market at a very high premium (more than 2x the price of our sleeving). Because of the outgassing produced by this resin, this particular fray resistant product is not approved for use by NASA.

We offer two simple solutions to this problem:

1) Since our braid is heatset, it has some inherent fray resistance. This will allow for easy installation without much fray. Cover the ends with heat shrink tubing (our Kynar Heat Shrink Tubing is a great solution since it's temperature rating is similar to that of Halar, and it's sold in 4 foot pieces).

2) Purchase a hot knife from us for $99. A hot knife is a great way to get a true non-fray end on your braided sleeving. Just simply turn it on, and run the sleeve down the blade, and the sleeve is cut very easily. Just make sure you're in a well ventilated area.

Bench Mount Hot Knife Cutter for Non-fray expandable sleeving

Look at the pictures below. The 1/2" sleeve (on the left) was cut clean with a sharp pair of scissors prior to being put on a 3/4" highlighter. It is clear that there is some end fray. This can easily be covered with heat shrink tubing to give a clean end. The braided sleeve on the right was cut with a hot knife. This end would be fine without any heat shrink tubing. You may want to put a cable tie on the end to stop the sleeve from slipping. In this case, we recommend our Halar Cable Ties.



Sleeving in these pictures is actually our PET Flame Retardant sleeving, as denoted by the contrasting color tracers
