摘要： Provided is a recyclable flame-retardant foamed styrene resin composition having high flame-retardancy and heat stability by adding little bromine-containing flame retardant. A flame-retardant foamed styrene resin composition containing (A) a styrene resin, (B) a mixture of (B1) tetrabromobisphenol A-bis(2,3-dibromo-2-methylpropyl ether) and (B2) another bromine-containing flame retardant, (C) zinc-modified hydrotalcite, (D) zeolite, and (G) a foaming agent, containing 0.005-0.08 parts by weight of (C) the zinc-modified hydrotalcite per 100 parts by weight of (A) the styrene resin.
