INJECTION FOAM MOLDED BODY

An injection foam molded body composed of a propylene resin composition, when a sample having a size of 50 mm×150 mm cut from the injection foam molded body is used to carry out a three-point bending test in which force is applied to the center position of the body with a distance between supports o...

Beschreibung
Zusammenfassung:	An injection foam molded body composed of a propylene resin composition, when a sample having a size of 50 mm×150 mm cut from the injection foam molded body is used to carry out a three-point bending test in which force is applied to the center position of the body with a distance between supports of 100 mm by an indenter at a bending rate of 50 mm/min, a bending elastic gradient within the range of 27 to 1,000 (N/cm), and when the injection foam molded body is subjected to a test in which a force (load) is applied to a flat surface thereof by a circular indenter with a flat tip having a diameter of 4 mm at a rate of 1 mm/min to push the indenter into the molded body, a press elastic gradient is in the range of 5 to 120 (N/mm).
