Glass, porcelain, plastic and rubber are examples of non-conductive materials. These materials are also known as insulators. They are used to stop the flow of electricity.Continue Reading
Insulators either prevent or block the flow of electrons. The atoms inside insulators do not have extra electrons that can move freely through a material. However, there is no such thing as a perfect insulator since an insulator can become electrically conductive.
The opposite of insulators are conductors. Examples of conductors include copper, aluminum, platinum, gold, silver, ionized water and trees. Conductive materials are compounds that are comprised of atoms with free electrons. These electrons are able to move freely through the conductive material and allow electricity to flow.Learn more about Atoms & Molecules
Porcelain was invented by the Chinese sometime during the Tang Dynasty, which lasted from 617 to 907 A.D. However, they had been making ceramics and proto-porcelain materials for as many as 1,000 years before this time.Full Answer >
Glass is a solid, brittle and usually transparent material, explains HowStuffWorks. It is amorphous, which means it is not made of crystals. The properties of glass can be varied by changing the materials used in its manufacture and the proportions in which they are used.Full Answer >
Glass, paper, Teflon and rubber are good insulators of electricity. An insulator is a substance that allows very little electric current to flow through it. There is no perfect insulator, but materials that offer a high degree of resistance to the flow of electrons are good insulators.Full Answer >
A list of polymers includes nylon, polystyrene, polyethylene, latex, nitrile rubber, collagen and gutta percha. Polymers are made up of long strands of repeating molecules.Full Answer >
