[Test-Equipment] OT: heat transfer paste

[Rasputin Novgorod]

I'm sorry for this off topic query, but I don't know
who else to ask.

I was cleaning and removing some power transistors and
regulators off heatsinks. Instead of the usual white
heat transfer paste between the transistor and sink,
some had no paste; just a thin rubber-silicon-like
pad. I presume the pad was for heat transfer and not
electical isolation, there was no attempt to insulate
the bolt.

Is this thin pad a new way to "heat transfer" these
parts? Is it better? It's certainly less messy.
What is this pad material? Vendor?

Sincerely,
