conductor
Generally speaking, a material that does not let electrons travel through it, a material that has a very high resistance to electron flow (electric current), is called an insulator.
Insulator
What you are referring to is called static electricity. It is defined as the accumulation of electric charge on the surface of a non-conducting (insulating) material. It is generally produced by friction or by electrostatic induction.
An insulating material is one that doesn't let something through easily. The "something" is usually either electricity, or heat.
A material that does not conduct (or allow the 'passage' of) electricity is called an "insulator".
Insulator
conductor
An insulating material, also known as a dielectric, is a material that does not allow the flow of electricity through it due to its high resistance to electrical current.
That refers to a material that doesn't let an electric current through easily - a material with a high resistance,
Insulators
An opaque material.
Generically they are called conductors.
