※1 Softening temperature measurement method: Vicat softening temperature (at temperature rise rate of 50℃/hour and load of 2.5N)was determined with a needle inserted by 1mm.
※2 Shrinkage：A film gate sheet (126mm x 126mm x 2mm)was formed (at mold temperature of 40℃ and cooling period of 40 seconds).
※3 This is a grade that is made to order and sold.
