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

Firstly, this should not be considered heat shrink tape. It is honestly not that shrinky. It should be instead called melt tape. THAT IS NOT A BAD THING!! It simply operates somewhat differently than heat shrink but offers way more benefits than electrical tape. Electrical tape his its place but has some major flaws, namely its adhesive doesn't last forever. But what if it did? We would use it a lot more over heat shrink. Well, that's where this stuff comes in handy. Since you legit melt it together, it cannot come apart. That is an instant benefit over electrical tape. Heat shrink comes in tubes so there are a lot of places where you just straight up cannot use it due to accessability reasons like wires being already bundled or terminated, the wire is entirely too long for the heat shrink, you dont have the right size of heat shrink, ect. This tape is super thin and flexy. You can use it virtually anywhere so long as it will not constantly be burning. No engine blocks. Do not. That said, I just purchased a new project vehicle, a 2007 4 door Jeep Wrangler JK with an infinity sound system. If I can tell you anything, it's that what ever maniac designed this sound systems wiring wanted to make sure it would never be removed. I had to rewire EVERY SINGLE BIT of the sound system (and then some). This stuff was used every time I spliced or terminated a wire *on top* of whatever premade heat shrink was on the connectors becuase I am going to do some horrible things to this jeep out in the middle of the woods. A little extra weather resistance will be worth it. Bottom line, buy it. You will not stop finding ways to use it after you understand its actual function and how to MAKE it function... which requires finesse.

This product should be a lot easier to use than it is . After reading the other reviews I decided to purchase it and try it out . I was able to do what I needed BUT it was difficult and took me more than a few tries before I got it right . There is a very thin line between it being shrunk and it burning up . Definitely use a lighter to attach the end to whatever you’re doing and then wrap but it’s the heat part after that that’s tricky . If you get too close , you’ll burn it . If you put too much heat on it , even from afar it will burn . The adhesive properties in this “tape” are not strong . In all honestly you’d be better off using regular tape or electrical tape if you can’t use regular heat sharing wraps . Would return but I’ve used quite a bit . Try at your own risk , it can work but it might take you a bit .

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.

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! 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.

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.

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.

But for places where I cannot disconnect the wires to slip on heat shrink tubing... this stuff works great.

The tape does not have any adhesive on it. You have to wrap it around tightly so it stays in place. Apply heat to it and it shrinks up. I used it on some boat wiring to an outside transducer. Once the tape was shrink wrapped around the wire, I applied some 5200 Marine adhesive on top of the tape and it worked great.

To sum up this product, it's utter trash. While not a professional in the electronics field, I have installed several car audio systems, repaired a number of gadgets, etc. over the years and have a good idea of how to use such materials. Nevertheless, I viewed some videos to ensure I understood how to use this tape properly. I'm certain heat shrink tape itself works well when utilised correctly. However, this particular brand is absolutely horrible. Though I gave it a fair chance by trying it several times, cutting and using new strips each time, it never shrank. A waste of money, time, and patience.
