Why is rubber a good electrical insulator.

Keeping electricity bound within the material is the main goal of an insulator making rubber a very good choice especially in the form of electrical mats. But i want to know why rubber is a good insulator. An electrical insulator is a material in which the electron does not flow freely or the atom of the insulator have tightly bound electrons whose internal electric charges do not flow freely. Plastics pvc cresyl pthalate dehp and other plastics replaced rubber as an insulator for wires and other parts.

Because rubber is a good insulator it is used on the outside of wires that are used to conduct electricity. Types and history of electrical insulation. Pvc and nylon are now standard in most types of wire. Why use electrical mats.

For example wood makes a good insulator due to the air pockets in it s biological structure. An insulator is a material that reduces or stops the flow of an electrical current. Without the proper safety equipment such as electrical mats workers are at risk of electrocution while performing their duties. I understand less dense materials make better insulators as insulators absorb trap heat.

2 list of common insulating materials solids. Rubber provides protection from the dangers of electrical charges being carried through the metal conductors. Closed cell sponge rubber is good because of its low thermal conductivity and great temperature resistance.
