Abstract
Nowadays, the companies use polymer materials for many purposes fur they have many advantages. The costs of these materials take up too high a proportion of the overall cost of products that use these materials as their major material. It is advantage for polymer industries to reduce these costs. The microcellular foaming process was developed in the early 1980s to solve this problem and proved to be quite successful. Microcellular foaming process uses inert gases such as $CO_2,\;N_2$. As these gases solve into polymer matrices, many properties are changed. The microcellular foaming process makes the glass transition temperature of polymers to low, and diminish the residual stress of polymer matrices. Besides, the microcellular foaming process has several merits, impact strength elevation, thermal insulation, noise insulation, and raw material saving etc. In previous research, many facts of microcellular foaming process are founded its characteristics. But previous researcher found the characteristics of microcellular foaming process with pure gas, for example $CO_2,\;N_2$ and so on, they did not found the characteristics of microcellular foaming process with one more gases. If one more gases inlet the resin, the characteristics of microcellular foaming process is changed very amazingly. In this paper, discuss on the characteristics of microcellular foaming process wi th gas cocktail about cell morphology.
