Polymer materials are normally regarded as materials of high electrical resistivity and are widely used as insulators. However, the incorporation of various fillers, additives or surface coatings can greatly reduce electrical resistance properties.
There are various technical and industrial purposes for which a polymer with a reduced resistivity is a useful material, the most frequent application being for the dissipation of static charges. Electrostatic discharge (ESD) can result in electrical shock to a person or create sparks which are very dangerous, especially in potentially explosive atmospheres.
