ABSTRACT:
A bushing assembly for forming fibers from a supply of molten fiberizable material has: (a) a bushing block having an insulating body with a bore extending therethrough and (b) an electrically conductive bushing positioned adjacent to the bushing block to receive molten fiberizable material from the bore. The bushing includes a flange having bonded to an upper surface thereof a primary layer of an electrically insulating material with a bulk density of greater than 2.0 grams per cubic centimeter. The electrically insulating material is positioned adjacent to the liner on the lower surface of the body of the bushing block and is in contact with the molten fiberizable material.
