  • Highly Filled Composite Containing Resin and Filler
    Publication number: 20100025879
    Abstract: A highly filled composite is formed by extruding through a multiple screw extruder a thermoplastic resin and sufficient filler so that an autogranulating extrudate exits the extruder barrel. The extruder is operated without an exit manifold, strand die or breaker plate. The extrudate forms irregularly shaped granules. The granules provide a molding composition that can be used to form highly filled molded articles such as fuel cell separator plates and end plates by compression, injection or compression-injection molding.
