Electrical conductivity

Electrically conductive materials, such as metals, have delocalized electrons that can easily move along a potential gradient. Electrons in the covalent bonds of organic molecules such as polypropylene must remain near their host atoms and are not free to move through the material; as a result, they are poor conductors of electricity. [782] The high dielectric strength and low dielectric constant and dissipation factor of polypropylene make it useful as an insulating material. [783, 642] Conductive materials such as carbon black can be added to a polypropylene formulation for applications requiring electrical conductivity. [698
