Abstract:
In order to obtain a flame-retardant polyolefin resin expanding molded product which has excellent in-mold moldability and excellent surface appearance and satisfies the FMVSS flammability even if carbon black is added, polyolefin resin particles containing, with respect to 100 parts by weight of polyolefin resin, (i) 0.03 part by weight to 5 parts by weight of phosphorous flame retardant having a phosphorous content of 7% by weight or more, a melting point of 120° C. or more, and a 5% by weight decomposition temperature within a range of 240° C. to 320° C. and (ii) 0.5 part by weight to 20 parts by weight of carbon black are expanded.
