ドアウト性も不充分である。(Prior art and its problems) Regarding the flame retardancy of thermoplastic resins, the technique of blending decabromodiphenyl ether as a flame retardant was disclosed in Japanese Patent Application Laid-open No. 5
No. 4-52152 is known. However, when making polypropylene and ethylene propylene block copolymer flame retardant with the technique disclosed in JP-A-54-52152, the bleed-out resistance of the [11 flame agent] is insufficient and the heat distortion temperature is low. Regarding flame retardant propylene polymers, Japanese Patent Application Laid-Open No. 59-74141 discloses a technique for blending decabromodiphenyl ether as a flame retardant.
JP-A No. 59-74152, etc. are known. However, these techniques have low bending strength, low tensile strength, and low heat distortion temperature, and also have insufficient flame retardant bleed-out resistance.

縁性などが低下する欠点がある。In order to obtain a sufficient flame retardant effect by blending an inorganic flame retardant and/or phosphorus compound such as magnesium hydroxide or aluminum hydroxide into polypropylene, a large amount of the inorganic flame retardant and/or phosphorus compound is required for K. However, if a large amount of these substances is blended, there is a drawback that strength, gloss, electrical insulation, etc. are reduced.
