Important Guidelines for Using PTFE Heat Shrink Tubing

Any time you need to bind wires together or insulate them, PTFE heat shrink tubing is an amazing solution to use. It will become smaller once heat is applied to it, which won't be a difficult task to complete if you look over these guidelines.

Be Careful When Heating the Tubing

When you heat PTFE heat shrink tubing over any type of wiring, it's going to be extra malleable. It's helpful that the diameter can shrink, but you'll need to be careful with your movements when it's in this state so you don't damage it.

Trying to stretch the tubing over sections or moving it the wrong way could cause the tubing to tear or puncture, and then you would have to find more tubing and start this heat shrink process all over again. Using extra precautions will save you these difficulties.

Consider Using Adhesive-Lined Tubing

If you want to ensure your PTFE tubing ends up remaining where you want it around wires, then you can look for tubing with adhesive linings. The adhesives inside are going to bond to your wire materials better.

So after you get down shrinking the PTFE down to the appropriate diameter, it will remain over wire sections that warrant insulation or binding. You thus don't have to go back and adjust the tubing or worry about the tubing shifting out of position over the years. The adhesive design saves you a lot of additional work.

Try Out a Couple of Different Sample Sizes

Getting the right size of PTFE heat shrink tubing is critical for the type of success you're able to see with these materials. Even if you know what size to get based on a certain shrinking ratio, it's still a good idea to get some different sample sizes. Then you can test them on wire materials to see how they end up fitting once they've been properly heated for the correct amount of time. Once you find a size that's optimal based on what you're doing with heat shrink tubing, you can order more of the same size in bulk.

Wires can be protected and insulated all thanks to the innovations made with PTFE heat shrink tubing. It has a lot of great properties and isn't that difficult to set up. You just need to make sure you're working with the right heat shrink tubing and follow simple instructions that yield optimal results. Contact a company like Tef-Cap Industries for more information.
