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. Pvc and nylon are now standard in most types of wire. For example wood makes a good insulator due to the air pockets in it s biological structure. Types and history of electrical insulation.

Sponge rubber when used as pipe insulation has great condensation resistance and thermal properties. 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. Because rubber is a good insulator it is used on the outside of wires that are used to conduct electricity. Plastics pvc cresyl pthalate dehp and other plastics replaced rubber as an insulator for wires and other parts.

Closed cell sponge rubber is good because of its low thermal conductivity and great temperature resistance. 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.

An insulator is a material that reduces or stops the flow of an electrical current. 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. Why use electrical mats.
