Abstract: A method for searching for statistics correlated with a strength of a pillar-shaped honeycomb formed body after firing having predetermined design specifications including a step of measuring two or more parameters for 90% or more of the polygonal cells excluding partial cells at the outermost periphery, and calculating two or more statistics for each parameter measured; a step of firing each of the plurality of pillar-shaped honeycomb formed bodies before firing under predetermined conditions to prepare a plurality of pillar-shaped honeycomb formed bodies after firing; a step of evaluating a correlation between the two or more statistics and the strength of the plurality of pillar-shaped honeycomb formed bodies after firing; and a step of determining a statistic having the highest correlation with the strength of the pillar-shaped honeycomb formed bodies after firing having the predetermined design specifications from among the two or more statistics.

Abstract: A method for manufacturing a pillar-shaped honeycomb fired body including: measuring a firing shrinkage at an end surface of a first pillar-shaped honeycomb firing body at every predetermined angle for one round based on a portion that has been located at the center of a die when a green body passes through the die, obtaining a second pillar-shaped honeycomb formed body having a corrected end surface contour by modifying an annular mask used for extrusion molding based on a result of the measuring, and then obtaining a second pillar-shaped honeycomb fired body by performing drying and firing.

Abstract: Provided are: a stabilizer composition that can not only impart excellent thermal stability, coloration resistance, thermal coloration resistance, and the like to a vinyl chloride resin, but also impart excellent transparency to a vinyl chloride resin when used in an application where transparency is required; a vinyl chloride resin composition containing the same; and a molded body thereof. The stabilizer composition contains 5 to 2,500 parts by mass of a component (B) with respect to 100 parts by mass of a component (A). The component (A) is at least one organic acid zinc salt, and the component (B) is at least one epoxy compound having a glycidyl ether group and/or a glycidyl ester group.
