摘要： The present invention provides rigid polyurethane foam comprising thermally expandable particles which are displaced to penetrate a strut of a structure of the polyurethane foam so that the particles are exposed into one or more cells of the polyurethane foam during foaming. Further, the rigid polyurethane foam can comprise hollow thermally expanded particles which are displaced to penetrate a surface of a cell in the polyurethane foam so that the particles are exposed into one or more cells of the polyurethane foam during foaming. The rigid polyurethane of the present invention can have excellent insulating properties.
