MYJOR Kapton Tape 4 Rolls Pack (1/4", 1/2", 3/4", 1") - High Temp Polyimide Tape for PCB Soldering, 3D Printer Bed & CPU Protection - Heat Resistant up to 500°F, Strong Adhesion, Clean Peel No Residue

Not exactly identical to Kapton tape, both in a positive and negative attribute. Pros: - Price for performance is excellent value - Excellent resistance to extreme temperatures. Measured through infrared and direct measurement found that - film deformation began at 673 degrees and at 769 degrees, while the film appeared to burn, it appears that it is the adhesive that carbonized as the film itself exhibited no perforations after being heated to nearly 800 degrees. YMMV, but these are the temps I observed when testing heat resistance - Physical dimensions and thickness is similar if not more robust than Kapton film. - Comes on a rigid plastic spool identical to genuine Kapton, not cheap cardboard or similar cheap material making them tough enough to toss into a electronics tool bag without concern Cons: The only complaint I would bring up is the relatively weak strength of the adhesive compared to brand name Kapton film and several similar products. This is not a deal killer as test adhesive will adequately hold in most applications as long as you clean the surface thoroughly before attempting to apply the film.

I use Kapton tape for protecting electronic components that I do not want to melt off of the circuit board when using my air desoldering station. This is just sticky enough to stay in place, seems to be the right film thickness (1 mil) and cuts like the mil-quality stuff. I have also used Kapton for a protective layer over loose radioactive materials when doing gamma ray spectroscopy. I had found that the old way of using scotch style tape would break down over a few years due to the constant radiation exposure. Kapton tape was intended for use on satellites and spacecraft so it is resistant to that type of deterioration. It blocks alpha particles but beta particles and gamma rays are barely attenuated.

This tape assortment came in handy when wiring a BMS to my Lithium battery pack. The thinner tape was for the individual wires and the widest for the wire bundles. It was a bit hard to get the tape started off the roll as it is thin but was able to use it fine once started. The quality is very good and the tape is strong. It's a great value for the price.

This tape works very well. I use it to position strain gauges for adhesion to a surface. After I remove the tape, it does not leave residue on the strain gauge. I also use this tape to position ARC Chips onto printer ink cartridges. After everything is properly aligned, I lift one side of the tape, which also lifts the ARC Chip, then I remove the plastic film from the self adhesive back of the Chip. I then fold the tape back down and stick the Chip to the ink cartridge. Permanently remove the tape. While the tape does not leave any residue; I still wipe the contacts of the chip with Isopropyl Alcohol (>90 percent). A Perfect alignment every time.

I was repairing an expensive Snap-On rechargeable flashlight. The USB-C connector had been mangled. Not only was the connector damaged, but the solder mask coating underneath the connector was scraped off by the connector causing a short circuit. Before soldering the new surface mound USB connector using hot air, I applied the tape to the bottom of the connector and another piece to the top of the damaged solder mask. The tape withstood the heat of the hot air soldering tool, and the flashlight has been working fine now. When you need to provide a high temp insulation or mask off other surface mount components, this tape will work for a lot less money than Kapton brand of tape. I would buy this again.

Bought this set for soldering projects and replacing game cart batteries. The tape held up fine and held what I needed in place. Also provided protection where it was needed. Good value and I love the different-size tapes. It allows me to choose exactly what I need to save on resources.

I am using this for a hobby application where I am trying to prevent electrical parts from touching each other and prevent shorts. This tape is very thin (just as described), but still seems to be very durable. It can be a little hard to use, at least in my application and with older and clumsier fingers, but once I get it into place it does the job. Getting multiple widths is also a great plus!

Tape works great for lithium battery building. I have built a number of batteries and this tape does a great job at holding wires in place and creating barriers between the cells and the wires. Seems the tape does not hold a lot of heat and holds even through multiple heat/cold cycles.

Good

Making a microwave furnace. Perfect for my needs

Super merci

Good value for the amount of heat tape.

Received the package and quickly tested with soldering iron heated to 300C° The tape did not burn and/or melt. This is good quality and correctly advertised product. Thank you.
