I found this tape after accidentally breaking the insulation on the thermistor leads of a new hot end I bought for my 3D printer.Using the tape was simple. I punched a small hole in a short segment of tape and placed in over the screw hole. Then I installed the thermistor before adding a second layer of tape with its own hole and finally the screw. At least, I think that's how I did it.Whatever the case, it has worked absolutely flawlessly ever since. Definitely recommended!It is worth noting that I exclusively use PLA, which prints at 200C. Other filaments may require greater temperatures. Still, considering the other review(s) mentioning how well this tape works in ovens, I don't think that will be an issue.

I used this to repair my kitchen range. My stove is from the 1960s. Yes, I could buy a new one, but I like the featured of this one, so I decided to repair it. The insulation on the wires providing electricity to the burners from the controls (Hi, Med, Low, Simmer) at the back of the stove were frayed & very brittle - I suppose from the heat of the oven over the years.Regular electrical tape would not work, because the heat can be as high as 500° - at that temperature, normal electrical in tape would melt.This tape was designed to be functional at 500°. It installed easily, & the adhesive worked well. I only used about 3' of the 50' (?), so I have plenty left for other projects.I'm very happy with how it worked.

Great feel and easy ability to dispense, but might be lacking in some circumstance, in sticking tight to the surfaces, which counters it's intended use. Otw, very happy.

Used this to isolate magnet wire from a fair-rite core for an amateur radio antenna transformer. Worked great and is still up making contacts

It takes the heat very well. I used it till 250°C and the tape, including its adhesive tolerates the heat.

I have had a beautiful dress watch that I I haven’t been able to wear for 15 years. As it turned out, the electrical impulses particular to my body were interfering with the battery on the watch! A friend of mine suggested buying some fiberglass tape, since glass is such a horrible conductor of electricity. So I covered the back of my watch with your tape and the watch has worked beautifully ever since. I can’t thank you enough for your product.

Excellent product.Do not rip, thick and very good adherence.I wish the label would stay on the product instead of being part of the plastic wrapping. This would help for when I need it again to buy it again. :) Not sure long term - will have to update the review if needed.

Bought this for fixing thermocouples to hot surfaces. Has worked well so far up to 95 degrees centigrade. Haven't used it above that temperature.

I used this tape to wrap a thermal fuse in a sandwich toaster. The fuse was rated at 290C and the tape seems to have no trouble holding up to this type of application. Good adhesion, easy to work with.

Used it to insulate a hybrid ferrite-silicone steel inductor choke. Did the trick. Pricey though
