[PROBLEMS] There is no risk of generation of toxic gas or corrosive gas even in contact with a flame, it has both flexibility, impact resistance and heat resistance, and there is no deterioration in quality and workability due to stickiness or bleed out. Providing flame-retardant resin compositions and molded products that can be used in a wide range of applications. A flame-retardant resin composition comprising 80 to 400 parts by weight of a metal hydroxide (Y) per 100 parts by weight of a propylene-ethylene block copolymer (X1), the propylene-ethylene Block copolymer (X1) is crystalline propylene-ethylene random copolymer component (A) in the first step, and low crystalline or amorphous propylene-ethylene random copolymer component (B) in the second step. Is obtained by sequentially polymerizing and is provided by a flame retardant resin composition that satisfies the following conditions (i) to (iii). (I) Melting peak temperature [Tm (A)] by differential scanning calorimeter (DSC) of copolymer component (A) is 90 to 140 ° C. [W (B)] is 10 to 90% by mass, and (iii) the ethylene content [E (B)] of the copolymer component (B) is 40 to 75% by mass. [Selection figure] None |
