A fundamental study of the microcellular foamed structure in rotational molding was conducted by using polymer microspheres as a blowing agent. The influence of the viscosity, temperature dependence of viscosity and first normal difference of different resins on the cell morphology and the tensile properties of the foamed parts was investigated.
