| abstract | (57) [Summary] [Problems] To obtain a low-density, high-rigidity polypropylene-based resin foam having few open cells. SOLUTION: The resin temperature is 210 ° C and the shear rate is 0.05. when increased from 0.1 at the rate of sec -1 / sec to 0.5 sec -1, natural logarithm of shear rate (X): ln X and the natural logarithmic value of the shear stress (Y): lnY, a relationship represented by the following expression (1): lnY = AlnX + B holds, and the value of B in the expression (1) is 6.1 to 9.0. And When the value of A is arbitrarily selected from the range of the value of B, one value is substituted into the expressions (2) and (3). The object is solved by a polypropylene-based resin foam made of a polypropylene-based resin having a value equal to or greater than 0.0362B + 0.915 and equal to or less than a value represented by the formula (3): A = 0.0397B + 0.948. |
