Conveyors, chutes, skids, guides, and ways for the transporting of
material are formed of a conductive loaded resin-based material such that
fragments of these structures can be detected by a metal detector. The
conductive loaded resin-based material comprises micron conductive
powder(s), conductive fiber(s), or a combination of conductive powder and
conductive fibers in a base resin host. The ratio of the weight of the
conductive powder(s), conductive fiber(s), or a combination of conductive
powder and conductive fibers to the weight of the base resin host is
between about 0.20 and 0.40. The micron conductive powders are formed
from non-metals, such as carbon, graphite, that may also be metallic
plated, or the like, or from metals such as stainless steel, nickel,
copper, silver, that may also be metallic plated, or the like, or from a
combination of non-metal, plated, or in combination with, metal powders.
