They call it "Hi-temp tape". It's sold as "masking tape" for powder
coating (so presumably it's good to 350°F or more), and I'd like to
track the specs down for another potential application.

I'm not sure what your application is but there is a tape made for masking
pcbs for wave soldering called Kapton tape (3M - Scotch 5413 Polyimide Film
Tape) It is good for continuous use up to 500 F.

You can find it at DigiKey.

Where I worked we used Kapton in vacuum chambers where satellite
equipment was being toasted by quartz lamps. It's pretty good stuff.
For our applications it not only had to resist heat but also not
outgass in vacuum. It's a yellow brown in color though.

I agree that Kapton (polyimide) tape is excellent stuff (aircraft
disasters notwithstanding). I'm trying to find something not *quite*
as good (but hopefully substantially cheaper).

Another brand in use at the same facility that's blue like the sample
you posted the URL to is sold by this outfit:

Lots o' tapes on that site, including some quite unusual ones. Thanks.
I don't see anything that's high temperature and that color (though
the color is immaterial with polyester).
