开孔分子式：CAS号：性质：(一)open pore 孔性固体中与外界连通的空腔和孔道称为开孔。不与外界连通的称为闭孔(close pore)。开孔与闭孔大多为孔性固体制备过程中形成的，有时也可在后处理过程中形成，如高温烧结可使开孔变为闭孔。(二)open cell 在软质聚氨酯泡沫塑料生产中，发泡过程后期，由于膜壁黏度较大，无法流动，同时弹性较低，无法承受膜壁的拉伸，从而造成气泡破裂，使气体逸出，这种现象称之为开孔。最有效的方法是调整催化剂或加开孔剂提高开孔率，将其混合在物料体系中，在泡沫塑料成型过程中影响体系表面张力，在适当的时候促使泡孔开孔化，防止制品收缩，改善柔性，提高制品的尺寸稳定性。其品种较多，可分为有机化合物、无机化合物和低分子量聚合物，如多胺，某些有机硅化合物，硝酸锆，多官能低分子量聚醚，低分子量聚苯乙烯等。也可采用机械方法开孔，开孔率高，软泡的回弹好。
