This is a 33 meter roll of polyimide tape. This tape is a fantastic insulator, like electrical tape, but it can withstand temperatures as high as 258°C (496°F). It also provides good resistance to corrosion and the silicone adhesive holds tight throughout the tape's rated temperature range. This is a good choice for insulating components inside of an enclosure that might be subjected to extreme conditions.

Very good stuff for wrapping Lipo Battery, Watt Resistor and it says Kanton on the tape . One interesting property of it is the ability to block high frequency visible light and possibly UV. I covered some area on a glow in the dark stickers and couldn't charge the covered area with bright LED ! I have seen people used it to as a masking pad for hand soldering smd on prototyping boards

This is awesome
Any of you who have used this stuff will readily agree: It is awesome.
I worked on high temp testing of directional drilling tools and we used this stuff EVERYWHERE. Wonderful wonderful stuff.
What about low temperatures? Will this stuff stay sticky below freezing? The datasheet only seems to mention the maximum of its rated range.
So to be clear, good electrical insulator but good heat conductor? And wouldn't this be useful double-sided for heatsinks...?
Yeah not a good heat conductor ... very much an insulator. I use this stuff extensively in my workplace. Its the equivalent of duct tape in how its used in semiconductor. We put this stuff through metal sputtering tools (high temperature, plasma, and bakes), high vacuum, HF and sulfuric acid etching, it blocks photo litho exposures but is still see through enough to align to something underneath if need be, blocks off reactive ion etching, and is otherwise a great electrical insulator. You can freeze it, its adhesive is not water based (its silicone based) and doesn't require preservation at low temperatures. We even use it for pull strength testing for ball mount pads sometimes. Adhesive cleans right off with IPA or acetone.
A post below mentioned its use in High vacuum systems, and yes is true that it will give off some gases from the adhesive. A miniscule amount and perfectly acceptable in most situations.
SparkFun offers this for use with heatsinks, it's a better heat conductor and it's double-sided.
Its also good for holding temperature probes when doing thermal profiling of ovens. Thermal profiling is important when working with expensive and temperature sensitive parts.
It is both a good electrical insulator and a good heat insulator.
I remember when this stuff used to be $5 a foot. At one place I worked we had to record the length we took from inventory. I was very glad when the price dropped.
Is this kapton tape? It looks like it. Makes a great solder mask for surface mount IC's that have long pads.
To anyone who's still interested, I just bought mine and it had a tag on it that seems to say Kapton. Here's a photo.
Its appearance and make appears to be similar to that of Kapton tape, but the adhesive may not be the same.
This is not the type of adhesive used for spacecraft. Silicone adhesives evaporate in a vacuum and stick to telescope optics, and are impossible to clean off. We are very strict about keeping silicone out of our labs at NASA.
It will work fine for non-vacuum applications.
Kapton is a brand of polyimide tape. So yes, basically the same stuff, but technically no because it's an off-brand.
This stuff is also the duct tape of 3d printers. I've got bits of it all over my Makerbot, and it's one of the best materials to make a heated build surface to keep prints from breaking loose before they're finished. You'll probably want a wider roll for that purpose, though.
