Abstract
Flame retardant polyolefin pre-expanded particles made of a resin composition comprising a polyolefin resin and a sterically hindered amine ether flame retardant, which can be molded with good moldability to give in-mold foamed articles which have an excellent flame resistance and do not generate harmful gas at the time of burning.
Claims8
A flame retardant polyolefin pre-expanded particle made of a resin composition comprising a polyolefin resin and a sterically hindered amine ether flame retardant.
A flame retardant polyolefin pre-expanded particle made of a resin composition comprising a polyolefin resin and a sterically hindered amine ether flame retardant, wherein said pre-expanded particle shows two fusion peaks on a DSC curve when measured by differential scanning calorimetry, and the heat of fusion QH of the peak appearing on the higher temperature side is from 1.5 to 25.0 J/g.
