Microcellular foamed plastics has significantly contributed to the plastics industry by achieving product’s weight reduction and material cost savings. Limitations in petroleum resource reserves have lately propelled active research into foaming process. In particular, the extremely small cell size at less than 10㎛ and higher density for microcellular foaming process compared to the existing chemical foaming keeps its mechanical property decline small. In short, microcellular foamed plastics keeps mechanical property decline to minimum and product light. The research into microcellular foaming process thus far focused on elevating foaming expansion ratio or keeping off mechanical property decline such as intensity Nowadays, one of the most important trends in the polymer field is the replacement of petroleum-based polymers with bio materials composite polymer. If you mix in a wood powder composite reduce carbon dioxide generation through the ecofriendly materials. This paper uses polypropylene, which is engineering plastic, to carry out foaming and describes research outcome of foamed Wood powder-composite polymer characteristics
