Liquid Metal Thermal 'Compound'

Yea it isn't mercury, because they couldn't sell it. And about conductivity, well, we don't know if it is conductive. If they have an alloy of "liquid" metals then they might have a non-conducting alloy. After all, Arctic SILVER 5 contains silver and is non conductive (capacative, but non conductive).

 

yeah max is right, something can have metal in it and not conduct, but it can/will have a capacitive (is that how you spell it?!) effect.
