The Study on Physical Properties of TPU Foam by CO2 Foaming Process |
| 초록 |
In addition to intrinsic properties of TPU , the form structures such as cell density, cell size, and cell thickness are other important factors to control the physical properties of TPU forms. Our previous study found out that form structures are strongly depend upon the CO2 foam processing pressure and temperature. Increasing forming temperature and pressure resulted in less density, larger cell size and thinner wall thickness. Optimum forming conditions were determined based on rheological properties of TPU. The hardness, mechanical properties, thermal conductivity and rebound resilience of the molded TPU forms were investigated and the influence of foaming conditions on these properties were related. It was found that the hardness, mechanical properties depend largely on density. Generally, strength characteristics increase with density. Rebound resilience decrease with increasing density. The effect of molding conditions on the physical properties were also considered as well. |
