The choice of fiber is determined not only by the level of conductivity required but also by the environment of the application. For example, electric fiber are based on polyester they are not suited to warm moist environments (in fact their maximum temperature is limited below regular polyester, maybe 110&deg;C).Steel electric fiber can be used with just about every filter medium. Acrylic, PPS, P84 and Nomex would almost invariably be used in conjunction with electric fiber.
