Polymers are typically classed as electronically insulating materials and are often used for insulation applications in electrical devices. However, there are many applications which call for traditional benefits of polymers over, for example, metals (low weight, no corrosion etc) whilst also requiring specific levels of electrical conductivity.
There are several methods available to impart varying degrees of electrical conductivity to polymers, depending upon the specific requirements of the application.
The below chart illustrates the conductivity ranges of surface resistance between unfilled plastics & metals:
CONDUCTIVITY RANGES - SURFACE RESISTANCE
KONDUCT can provide the following services, based on your material and specific performance requirements:
Insulative – Materials whose internal electric charges do not flow freely and very little electrical current will flow through under the influence of an electric field. Most unfilled polymers fall into this bracket.
Conductive – Materials that have very low electrical resistance, with electrons flowing easily through the bulk of the material or across the surface.
Static Dissipative – Here, electric charges flow more slowly and in a more controlled manner. Such materials are typically used to prevent discharge to/from human contact.
Anti-Static – Such materials inhibit the build-up of electro-static charges and provide the route for a very slow rate of decay.
