• Flexible polyurethane foams having junction modifying particulate additives

  Conventional polyurethane foam products are modified by incorporating into the urethane reaction mixture a junction modifying particulate material that is selected with a critically controlled particle size relative to certain dimensional parameters of the foamed polymer matrix. This particulate material is selected with a particle size that results in location of the material in the foam cell wall junction regions rather than in the cell walls. The resulting products provided excellent physical properties (such as modulus of compression, tensile strength, elongation and tear resistance) at lower costs than normally encountered with similar unmodified foams. The preferred junction modifying particulate materials are organic polymeric materials such as ground rubber or plastics. As a result, the large particle size materials needed to achieve the junction modifying properties can be used without causing harmful abrasion or wear of processing equipment surfaces.

  传统的聚氨酯泡沫塑料产品是通过在聚氨酯反应混合物中加入结点改性微粒材料进行改性的，这种微粒材料的粒径相对于发泡聚合物基体的某些尺寸参数而言受到严格控制，这种微粒材料的粒径可使材料位于泡沫塑料细胞壁的结点区域而不是细胞壁中。 由此产生的产品具有优异的物理性能（如压缩模量、拉伸强度、伸长率和抗撕裂性能），而且成本低于通常使用的类似未改性泡沫塑料。 优选的结点改性微粒材料是有机聚合物材料，如磨碎的橡胶或塑料。 因此，可以使用实现结点改性性能所需的大粒径材料，而不会对加工设备表面造成有害的磨损。
