High melting point, low strength double sided tape

This is admittedly very niche…

I want some double sided tape that will work at high temperatures (multiple hundred degrees C) but I don’t want it to be too strong – want to be able ot pull it off by hand/fingers, even when cold.

All the fancy high temp stuff generally bangs on about how strong it is too, which I dont really want. But I dont know much about tape and therefore don’t know what the figures mean.

Anyone happen to be a tape expert?

It is a long time since I last specced an adhesive, but if 3M don’t have something in their product list then I’d say it is unlikely to exist.   It feels unlikely to me that there is any adhesive that is non-permanent and doesn’t get softer/weaker at high temp.

this was my gut feel too.

I wouldnt mind loss of strength at high temp as long as strength returned as it cooled, and it didnt leave a sticky mess

What’s the stuff that’s used for door seals on ovens and wood burners? Cooler than your spec perhaps though.

Kapton tape? Rated to 400 deg c I think?

RTV silicone?

No idea about double sided but polymide tape is what they use in powdercoating. High temp low adhesion (well, “easily removed” might be strong in shear and easy peel).

Edit: And sure enough adding “double sided” to “polymide tape” in google… Suggests it is a thing.

Silly question but, what are you trying to do? IANATE but we do use adhesives and tapes at work.

Polyimide Tape is ok, but not very sticky in my experience (or flexible). it’s ok for masking things, but if you want a D/S tape to grip two materials together it’s not great.

The best solution i’ve found is stacking materials: We use an acrylic D/S tape to apply some fixing clips to a component for painting so needs to be temp resistant (although not to 200°C), but we then need to remove the clips and leave no residue so we stick the D/S acrylic tape to the back of some high temp low residue masking tape on the back of the part.

The fireproof/resistant Velcro is pretty good, we used to use it to mount electrical equipment into cabinets. The standard Velcro products were rubbish though once things got warm.

Depends what you mean by removable, one component being put in and out repeatedly, or being able to remove the component and take the tape off completely leaving it clean?

+1, we used to use a lot of Tesa’s cloth tapes as a base to stick something too as in general they were pretty tenacious but came off cleanly. So you could stick something like 3M VHB tape to the component, know that it was going nowhere, but still have a chance of getting it off afterwards by spraying sticky stuff remover onto the cloth tape.

Self amalgamating tape is very good for very high temperatures and also wet surfaces, I’m not sure whether it’s weak enough to tear off with bare hands but that may depend on how many wraps you do. It might help us help you if you give us some context?
