摘要
The present invention, using an ethylene-propylene copolymer resin having a specific property to the base resin, is to provide a foaming resin composition using a metal deactivator as upon foaming nucleating agent. [MEANS FOR SOLVING PROBLEMS] Karu the present invention, the base resin fracture tension 5.0g or more at the time of melting (190 ℃), ethylene propylene copolymer resin (190 ℃, 2.16Kgf) is equal to or greater than MFR1.0g / 10min then, and to this as a nucleating agent, triazole and 3- (N- salicyloyl) amino-1,2,4-triazole, of hydrazide-based 2 ', 3-bis [3-[3,5-di tert- characteristic is in the foaming resin composition is made by adding a metal deactivator such as butyl-4-hydroxyphenyl] propionyl] propionohydrazide, thereby aims to high expansion degree of miniaturization and the foam cell, excellent It is possible to obtain a foamed resin molded article. None [Selection Figure]
