(#) - Once the polymer has been manufactured, it needs to be compounded into a suitable material for use in high voltage insulators. Polymer compounding is the science of mixing the polymers discussed above, with other chemicals to produce a polymer compound which has specific properties for an application. Examples of polymer compounds could be chewing gum, a garden hose, tires, solid rocket fuel, and of course, electrical insulators. Polymer compounding will be discussed in more detail in a later section.
