Polyester resin composition

摘要

PROBLEM TO BE SOLVED: To provide a polyester resin composition capable of obtaining a thermoformed product having excellent moldability and heat resistance without the load of expansion of equipment or the like. The polyester resin composition of the present invention contains a polyethylene terephthalate resin (A) and a deflection temperature adjusting agent (B). Here, the polyethylene terephthalate resin (A) can be crystallized, and when the polyethylene terephthalate resin is crystallized, the minimum value of the tensile strength of the polyester resin composition in the temperature range of 150 ° C. to 220 ° C. is 5 MPa or less. Yes, and the tensile elongation in the temperature range is 50% or more. [Selection diagram] None
