US 2025/0051512 A1 · POLYBUTYLENE TEREPHTHALATE RESIN COMPOSITION, METHOD OF PREPARING THE SAME, AND MOLDED ARTICLE INCLUDING THE SAME

Abstract

Disclosed are a polybutylene terephthalate resin composition, a method of preparing the same and a molded article including the same. The polybutylene terephthalate resin composition can provide an excellent physical property balance between mechanical strength and flame retardancy at a level equivalent to or higher than that of a polyester resin composite material containing a halogen-based flame retardant, has excellent processability due to excellent flowability, and is specifically suitable as a material for automotive electronic components.
