insulator

If the skull was an insulator it'd make EEG really hard.

It's also used in space launchers as heat and noise insulator inside nose fairings.

No, mineral oil as they're using it, with required specs, is an even better insulator than air

Which is mostly limited by the dielectric constant of the wire's insulator.

With a second printer head added, it should be possible to deposit thermal insulator right within a wall.

Unlikely to really affect a module inside the frame, especially if that module is wrapped in an insulator.

Amazingly, because cork it's such a great insulator burned cork trees survive the fires and develop very easily.

That tends to lead to suspicion of new technologies, especially new forms of communication that might short out the insulator.

Vacuum is an insulator against mechanical heat transfer, but it doesn't do anything against radiative heat transfer.

For a capacitor two conductors separated by an insulator - any conductor - any insulator - any shape.

It's impossible to make things without unwanted series/parallel resistances because conductors/insulators aren't perfect.
