A shim stack foaming die for making foam slabs comprises a plurality of shims that are layered together under pressure to form a shim stack, wherein the shims combine to collectively define a plurality of die orifices in a working face, to define a main body of the shim stack foaming die, and also to define a plurality of die cavity that is fluidly connected to the plurality of die orifices. And articles foamed from the shim stack foaming die have found wide use in various applications, thermal or acoustic insulation, reinforcing layers and/or space-filling layers, and so on. 本发明提供了种用于制备泡沫板的垫片堆叠件发泡模具，所述发泡模具包括多个垫片，所述多个垫片在压力下层叠在起以形成垫片堆叠件，其中所述垫片组合起来在工作面中共同限定多个模孔，以限定所述垫片堆叠件发泡模具的主体，并且还限定流体连接到所述多个模孔的多个模腔。本发明还提供了由垫片堆叠件发泡模具发泡而得的制品，所述制品已广泛用于各种应用，用于隔热或隔音、用于加强层和/或空间填充层等等。
