摘要: 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.
摘要翻译: 通过多螺杆挤出机挤出热塑性树脂和足够的填料形成高度填充的复合材料,使得自流平的挤出物离开挤出机筒。 挤出机在没有出口歧管,股线模具或断路器板的情况下运行。 挤出物形成不规则形状的颗粒。 颗粒提供一种模塑组合物,其可用于通过压缩,注射或压缩注塑成型形成高填充模制品,例如燃料电池隔板和端板。
