POLYOLEFIN RESIN PRE-EXPANDED PARTICLES AND POLYOLEFIN RESIN IN-MOLD EXPANSION-MOLDED ARTICLE COMPRISING POLYOLEFIN RESIN PRE-EXPANDED PARTICLES

摘要

It include that polyolefine resin composition contains polyolefin resin by forming polyolefin resin pre-foamed particle, bulky amine ether flame retardant (1) formula indicates: R1NHCH2CH2CH2NR2CH2CH2NR3CH2CH2CH2NHR4, phosphate, the resin pre-foamed particle of fire retardant polyolefin shows excellent flame retardancy, it is larger even for sample density with higher or thickness, compared with traditional, and pernicious gas will not be distributed, burning can be provided, expansion molding in good mould is kept simultaneously, without the use of halogen fire retardant.
