| Abstract: | In this paper ,the microcellular foam plastic of PP that made by second-opened moulding is introduced ,and the process parameters of injection that influcence the microcellular foam mechanical behavior of PP were studied in detail, So the best injecting precess parameters of microcellular foam plastic of PP is found. The microcellular foam plastic of PP that made by this process have better mechanical properties and the cell is well-distributed, the diameter of cell was 201axn to 30taan, the density is reduced about 15%. |
