PROBLEM TO BE SOLVED: To provide the combustion characteristics similar to those of a wood and improve the resistance to impact and rigidity by using a polyester resin composition having the specified heat development amount at the time of combustion and combustion residue after combustion for an injection molded product. SOLUTION: An injection molded product is manufactured by using a polyester resin composition blended with polyester resin prepared by polycondensating aromatic dicarbonic acid or its ester with glycol, and also, if required, with polyolefin resin, an olefin thermoplastic elastomer, a stabilizer and the like. At that time, the combustion heat development amount at the time of combustion is set as 5800-8000Kcal/kg, and the combustion residue after combustion is set as 1wt.% or less. The characteristics similar to those of a wood can be provided and the resistance to impact and rigidity at the time of dropping or or applying an impact can be improved by the arrangement. |
