Abstract

Abstract: Microcellular polymer material is a newly developed polymer material which cell size is in micron.Because its unique micro-pore structure can improve the dimensional stability, shrinkage rate and other shortcomings of products, which makes it become a research hotspot of polymer material in recent years.In this paper, the mechanism of micro-foam molding was briefly introduced, the effects of molding processing parameters, nano filler, blowing agent on structure and properties of microcellular polymer material were outlined.Summary was generated based on the numerous research results, then some critical issues that to be further studied was put forward.Moreover, the foreground of research and application of microcellular polymer was expected.All these fundamental works are very important for understanding the mechanism of forming of microcellular polymer foams.They are significant for subsequent application research as well.

Key words: microcellular polymer, molding mechanism, nanomaterials, blowing agent
