摘要： Provided are polypropylene-based resin expanded beads capable of providing an expanded beads molded article excellent in flame retardancy and also excellent in fusion-bonding characteristics of expanded beads to one another, and a method for producing the polypropylene-based resin expanded beads.
The polypropylene-based resin expanded beads (20) is configured to include an NOR type hindered amine and has a surface on which a thermoplastic polymer layer (22) is located, in which a blending ratio of the NOR type hindered amine in the polypropylene-based resin expanded beads (20) is 0.03 wt% or more and 0.5 wt% or less, and a blending ratio of the NOR type hindered amine in the thermoplastic polymer layer (22) is less than the blending ratio of the NOR type hindered amine in the expanded beads (20). Further, the method for producing the polypropylene-based resin expanded beads (20) includes a covering step and a foaming step, in which in the resin beads (10) to be obtained in the covering step, a blending ratio of the NOR type hindered amine in the resin beads (10) is adjusted to be 0.03 wt% or more and 0.5 wt% or less, and a blending ratio of the NOR type hindered amine in a thermoplastic polymer layer (12) is adjusted to be lower than the blending ratio of the NOR type hindered amine in the resin beads (10).

摘要： Provided is a propylene-based resin composition that can be molded into molded bodies that have high thermal stability and emit less odor. The propylene-based resin composition contains (A) a propylene-based polymer, (B) an inorganic filler; and (C) a hindered amine light stabilizer. The amine compound concentration in a volatile gas generated when a molded body formed by molding the propylene-based resin composition is heated at 100°C for 15 minutes is 3 to 40 mass ppm.
