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. -- -- Steve |

What kind of tape is this?
Hi,
here's a photo: https://www.pendrypowdercoatings.com...emp%20Tape.JPG 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?

Best regards, Spehro Pefhany 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. -- Al Clark Danville Signal Processing, Inc. -------------------------------------------------------------------- Purveyors of Fine DSP Hardware and other Cool Stuff Available at http://www.danvillesignal.com |

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: http://www.tycoadhesives.com/site/co...ape_search.asp |

They appear to be polyester tape with silicone adhesive, so nothing new. I suppose they soften along with the polyester powder at the Looked like polyimide according to the manufacturer's site. Do you want to use this as a stencil for anodized aluminium instrument panels? |

Hey Speff- I have a couple rolls of the 3/4" wide Kapton left over from a previous contract. Say the word and I will send them off to Trexon. Free for nothing. --Winston |

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

Martin 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.. http://rshughes.com/products/021200_88676.html You only have to buy one (master) roll, but it's $1500.00. 8-( Best regards, Spehro Pefhany -- "it's the network..."
