Abstract: The present invention addresses the problem of enhancing the fluidity of a polybutylene terephthalate resin composition that uses a halogenated benzyl acrylate-based flame retardant as a flame retardant while maintaining properties such as excellent mechanical strength that a polybutylene terephthalate-based resin possesses. The problem is solved by adding a protic compound to the polybutylene terephthalate resin composition that uses a halogenated benzyl acrylate-based flame retardant as a flame retardant.

Abstract: A method for improving the comparative tracking index of a thermoplastic resin, as measured in compliance with IEC60112, 3rd edition, is disclosed by blending a carbodiimide compound in the thermoplastic resin; use of a carbodiimide compound for improving the comparative tracking index of a thermoplastic resin, as measured in compliance with IEC60112, 3rd edition; and a tracking resistance improving agent for a thermoplastic resin, for improving the comparative tracking index of the thermoplastic resin, as measured in compliance with IEC60112, 3rd edition. The carbodiimide compound is preferably used at a ratio of 0.01 parts by mass or more with respect to 100 parts by mass of the thermoplastic resin.
