Why Is Rubber A Good Electrical Insulator

But i want to know why rubber is a good insulator.

Why is rubber a good electrical 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. 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. Why use electrical mats. Plastics pvc cresyl pthalate dehp and other plastics replaced rubber as an insulator for wires and other parts.

2 list of common insulating materials solids. Without the proper safety equipment such as electrical mats workers are at risk of electrocution while performing their duties. For example wood makes a good insulator due to the air pockets in it s biological structure. Clay ceramic porcelain this is the standard material for high voltage and rf insulators.

Because of the thermal properties spon. An insulator is a material that reduces or stops the flow of an electrical current. Sponge rubber when used as pipe insulation has great condensation resistance and thermal properties. Pvc and nylon are now standard in most types of wire.

Rubber provides protection from the dangers of electrical charges being carried through the metal conductors. I understand less dense materials make better insulators as insulators absorb trap heat. Very little electric current will flow through it under the influence of an electric field this contrasts with other materials semiconductors and conductors which conduct electric current more easily.
