A good conducter of what?
A vaccum contains nothing, no gas, no matter, no sub-atomic particles so it cannot conduct anything.
But particles and waves can travel through it, like light or radio waves.
After the published tables the silica aerogel is a very good thermal insulator. A vacuum, as in devoid of any matter.
Samarium is a good conductor for heat and electricity.
It is a very good conductor.
No, terylene is not a very good conductor of electricity.
No. Cheese would not be a good conductor.
nope
Vacuum is a good radiation conductor, and on a good day, the sunshine feels warm. Air is less good, but still a fair conductor.
A vacuum is a non conductor.
There are three modes of conduction of heat :-1.conduction2. convection3. radiationheat flow through vacuum comes under heat flow through radiation. Im this case heat acts as an electromagnetic wave , as these waves can propagate through vacuum energy is transferred even though there is no contact between the source and the drain(sink/destination .... whatever).Note :- Actually we discussions pertaining to the matter weather vacuum is a good conductor or bad conductor are inappropriate as vacuum is not a material to discuss its properties, its just like asking give me a dozen of water(i am not intentionally sarcastic i just want to explain how weird it is to say that vacuum is a good conductor).
Very good. Used in vacuum tubes and barred recently from high tech electronics.
A complete vacuum.

Air is a relatively-very-poor electrical conductor. If it were any good as a conductor,then you would need to keep your spare batteries in vacuum containers, to preventtheir becoming discharged through the air between their terminals.
A conductor is a substance that allows heat or electricity to pass through. A few examples of conductors are:WaterMetalAir (although not a good conductor is still a conductor)graphiteSalts and solutions of saltsPlasma (ionized gas)Vacuum that contains free electrons or ions
Something soundproof or near sound proof. A vacuum, for example.
