Mafuken 1 inch x 180 feet Black Heat Shrink Tape Non Adhesive (A)

I completely agree with a methodology that’s described by a reviewer. For reference I am copying it below. The only thing I would add that to hold the ends of the tape I just used two banana clips at the ends after I finished the wrapping. Indeed with the heat gun needs to be set up low. With that in mind, I was able to finish the shrinking process relative easily. . I had a few 5 inch wires that were part of a bundle that I could not take apart. So I could not use the traditional heat shrink tubing. This tape did the trick for me. For reference this is the methodology I was referring to: Here are instructions for how to use this product: 1) Wrap the wire connecting tightly about 6 or 8 times around 2) Cut the end of the tape with scissors to leave a clean edge 3) Singe the cut end of the tape with a lighter. This will soften the edge and make it sticky. 4) Stick the singed edge down onto the tape. Now it should hold together. 5) Using a heat gun on LOW setting, blow heat onto the tape. 6) As you heat, you will see it go from a flat/matte color to a gloss. 7) Continue heating until the whole thing is softened up. 8) Remove heat and let it cool. As it cools, the tape will harden up Here's what people do wrong with this product... - Complain that the loose edge doesn't stick (fixed this with lighter trick) - Complain that it doesn't shrink (it does, I laid out an 8 inch strip and it shrunk by 1/4 inch when using the heat gun) - Try to shrink it with a lighter or a heat gun on HIGH (which is too hot and will melt the product) Note that this stuff is much thinner than heat shrink tubing. I can do heat shrink tubing all day with a lighter. This stuff takes a much more delicate touch. But for places where I cannot disconnect the wires to slip on heat shrink tubing... this stuff works great.

Hard to imagine what this is supposed to be used for ... reminds me of PTFE plumber's tape more than anything else. Wrapped it tight in multiple layers, zip-tied the loose end, hit it with a heatgun and completely useless. No shrinkage or binding and can simply be unravelled.

I am writing this because I saw a few negative reviews saying the product did not work. This almost discouraged me from purchasing, but I'm glad I did anyway. At first, I couldn't get it to work. But after a few attempts, I came up with a method that works great!

First off it’s not really a tape cuz there’s no adhesive to help with sticking to the objects. You will have to figure out how to tie it off at one end then wrap them the way you want them to sit. I would recommend more than 2 wraps to make it thicker so after you heat them, it will bond better. 2nd recommendation is to use a candle or a high heat gun to heat up the “tape”. If you’re using the candle, make sure you’re in a well ventilated area because it stinks when burning them with a lighter or candle. I don’t think it will stink as bad using the heat gun. Once it’s hot and ready to mold, I would recommend wetting your hand or fingers so you don’t burn yourself. It will become mold a able to be able to grip the objects. And when done molding, run it under water to help it cool down and tighten the grip. I bought this to see if it would work better for my trolling lures and I would have to test it out. Just hoping it works. Had a hard time finding the right size ID shrink tube and saw this. Giving it a try for the first time.

Having read the "proper way to use this" reviews, I really want to like this stuff, but as far as I can tell it's basically electrical tape (same finish, same strechiness, same response to heat) but without the adhesive. This is called "heat shrink" and "tape" but based on my experience it is neither. It does not shrink the same way that heat-shrink tubing does. It shrinks more like electrical tape, which is to say that by the time it's hot enough to shink, it's hot enough to melt (it may be that my heater is too hot -- the one I'm using is actually for paint stripping, so my 'low' setting may be too high -- but it works fine for actual heat-shrink tubing!). Since there's no adhesive on it, I end up using electrical tape to hold the loose end in place, which leaves me wondering why I didn't just use electrical tape for the whole wrap! I guess next time I'll try the 'melt the loose end with a lighter' technique, but that means I need to keep a heat gun *and* a lighter around. I could see this being more useful on pipes or larger-gauge wires. For small wires it's a real pain.
