Please help me find this product. It is used in power supplies between the case and transformers. I read that it is a dielectric with a heat sink. The substance is a little soft.
Here is a photo.
Thank you.
Welcome to the TechForum.
That would be some sort of thermally conductive paste or putty meant to possibly help stabilize parts and definitely to help pass heat to the heat-sink frame along the sides of your supply. You would find them in this category:
-
Fans, Blowers, Thermal Management - Thermal - Adhesives, Epoxies, Greases, Pastes
-
Here’s a link to some of the more likely candidates for the particular type you have there.

Hi panov.vitaliy, David’s list is a good place to start. There is a wide array of possible options, but it’s safe to say this is a thermal compound as described. They are going to vary in viscosity and thermal conductivity, but at the end of the day quite a few of these will end up being appropriate for the application at hand.
Without knowing the exact specifications of the original material you’ll simply have to use your best judgement.
Thank you very much. I will choose something from you today. Tell me if you have flux for soldering stainless steel and aluminum? acid?
Well I do not see anything that tells me what type of flux you can use for each applicaton. I can provide a link to what we sell.
I started to look through data sheets and they do not provide this information either. Hopdfully someone can help on this one.
DigiKey does not carry flux materials that would be suitable for soldering aluminum/stainless steel. Such materials are quite different and more aggressive than those used in the electronics industry served by DK.
this substance in the power supply is solid. a little soft if you press on it with your finger. like rubber. it seems to me that what you wrote to me is a heat-conducting paste. like for computer processors.
See also the the Glue, Adhesives, & Applicators family. This is where products more focused on adhesion and mechanical properties (as contrasted with thermal interface) are found.
A non-corrosive RTV silicone product such as P/N 234325 might be the sort of thing that was used, or something with similar properties.
Within the link of parts I previously provided, these epoxy-type products might also be similar.
