What kind of tape is this?

[Steve Dunbar]

It might be Kapton tape, although the Kapton I've used was orange-colored.
We used to use it on electronic connectors that were being overmolded, to
keep the molten plastic from flowing where it wasn't wanted.

Hi,

here's a photo:

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.

Methinks that this is teflon tape, which is hi-temp stuff until it burns
and outgasses some nasty stuff. Very slippery stuff. Almost feels oily,
and you have to grab it just right to handle it. Trying to recall who makes
this kind of tape.... Scotch? Permatex? Permacell?

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.

Thanks, Lewin,

They appear to be polyester tape with silicone adhesive, so nothing
new. I suppose they soften along with the polyester powder at the
~400°F cure temperature, but the silicone adhesive keeps them from
sticking permanently. I don't think I've seen the translucent green &
blue colors before.

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.

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

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).

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).

There are some high temp tapes used in Plasma spray coatings
here are a couple of links

Looked like polyimide according to the manufacturer's site.

Do you want to use this as a stencil for anodized aluminium instrument
panels?

They are non-specific on the colors vs. materials. I think if it's
polyimide it's going to be amber, if it's polyester it could be
anything.

A selector guide of sorts -

Look over the class 1 masking tapes - the 2693 is a good start. There are
several to check - and make price cut based on volume of total world market.
Maybe the 2380 in class II. (Cheaper by class I bet)

Then searching for powercoat :
3M™ Composite Bonding Tape 8905, 10 in x 72 yd, 4 per case
[click to enlarge]

Clean removing high temperature silicone adhesive and tough
non-slivering polyester backing makes this tape a popular
choice for powder coat paint masking. 6.6 mil (0.17 mm)
total thickness.


3M Id : 70-0063-1697-3 << this one looks like a baking at 350F for 5 hours
and up to 400F...
GTIN(UPC/EAN) : 0 00 21200 55208 3

Don't know the prices - have to check them out.

Thanks, Martin, 3M has a much nicer search engine.

That much Kapton tape would probably run $500 or more (50+ 3/4" rolls
minimum order). Polyester should be cheaper.

I've also had trouble getting smallish quantities of such common 3M
adhesives as 46xMP (basically just a permanent acrylic adhesive with
two backings). Here's the sort of thing..

You only have to buy one (master) roll, but it's $1500.00. 8-(
