Insulator
A salt solution in water is a conductor, due to the disassociation of the salt molecules into oppositely charged ions in the presence of the polar water molecules. A salt solution in a nonpolar solvent would likely be an insulator, as the salt molecules probably would not dissociate.
Sulfur is a nonmetal. Nonmetals are bad conductors, while metals are good conductors. Since sulfur is a bad conductors, it is a good insulator.
It's a good conductor of current flowing in one direction, and a good insulator when current tries to flow in the other direction.

salt water is a good conductor of electricity as it contains sodium and chloride ions to carry out current

It is an insulator because it contain salt water in it.
it is good heat insulator, as it has air in it. as air is a good insulator of heat, the sponge, which has lots of pockets of air also becomes a good insulator
it depends what type of insulator youre talking about. wood is a good thermal insulator and rubber is a good electrical insulator A perfect vacuum is the best insulator.
