Abstract
The structure of microcellular foamed plastics causes optical, acoustic, and electrical properties. The diffuse reflection performance of microcellular foamed plastics can be applied as a high performance diffuse reflector. To improve microcellular foaming process, a simulation was conducted. It was to analyze the factor affecting when microcellular foamed plastics realized the diffuse reflection performance. Cell morphology of microcellular foamed plastics can be expressed through four factors. From result of simulation made a data base about cell morphology and diffuse reflectance. And the statistical method was used for identify contributions by factors.
