    摘要: Systems and techniques for forming microcellular polymeric material, via injection molding, blow molding, continuous extrusion, or the like, at very low blowing agent levels, are described. The invention involves, in one aspect, the discovery of a region of very low blowing agent level where, surprisingly, microcellular material can be formed. Articles with particularly good surface properties are provided.
