Why Is Rubber A Good Electrical Insulator

Why use electrical mats.

Why is rubber a good electrical insulator.

Because of the thermal properties spon. Types and history of electrical insulation. Clay ceramic porcelain this is the standard material for high voltage and rf insulators. Plastics pvc cresyl pthalate dehp and other plastics replaced rubber as an insulator for wires and other parts.

But i want to know why rubber is a good insulator. Without the proper safety equipment such as electrical mats workers are at risk of electrocution while performing their duties. Pvc and nylon are now standard in most types of wire. Closed cell sponge rubber is good because of its low thermal conductivity and great temperature resistance.

An insulator is a material that reduces or stops the flow of an electrical current. Rubber provides protection from the dangers of electrical charges being carried through the metal conductors. 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. 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.

For example wood makes a good insulator due to the air pockets in it s biological structure. Because rubber is a good insulator it is used on the outside of wires that are used to conduct electricity. Sponge rubber when used as pipe insulation has great condensation resistance and thermal properties.
