PURPOSE:To provide an electrically conductive filler composed of milled fiber of metal-coated glass fiber, miscible and dispersible readily in a resin, giving excellent electromagnetic wave shielding, electric wave reflecting and antistatic properties, and suitable for electrically conductive paint and electrically conductive plastics. CONSTITUTION:Glass fiber monofilaments are cut to proper length, and milled e.g. with a ball mill to fine milled fiber having a length of preferably 20-500mum and a thickness of preferably 3-23mum. The milled fiber is coated with a metal (Ni, Cu, Ag, etc.) e.g. by chemical plating at a thickness of 0.1-5mum. As an alternative method, the glass monofilaments are coated with metal and pulverized with a mill. The metal-coated milled fiber is compounded to a plastic as an electrically conductive filler.
