FLAME RESISTANT RUBBER MODIFIED POLYMER COMPOSITIONS

摘要

The present invention is a flame resistant resin composition comprising: a) from 50 to 90 parts by weight of a rubber modified polymer derived from a vinyl aromatic monomer, b) from 1 to 8 parts by weight of an impact modifier, c) from 0.5 to 5 parts by weight of a polyolefin having a density of greater than 0.940 g/cm<3> and a melt flow rate of less than 4 as measured according to ASTM D1238 at 190 DEG c using a 2.16 kg weight, d) a sufficient amount of a halogen-containing flame retardant to provide the composition with 7 to 14 parts by weight halogen, and e) from 2 to 6 parts by weight of an inorganic flame retardant synergist.
