Note) Typical values are only for material selection purpose, and variation within normal tolerances are for
         various colors.
         Values given should not be interpreted as specification and not be used for part of tool design.
         All properties, except melt flow rate are measured on injection molulded specimens and after 48
         hours storage at 23℃, 50% relative humidty.
