Ester-based plasticizer composition and use thereof
An ester-based plasticizer composition and uses thereof are disclosed. The ester-based plasticizer composition can provide a synergistic effect in the improvement of thermal stability, such as migration resistance and heating loss, to contribute to the enhancement of properties of a molded product. A molded product made from the ester-based plasticizer shows excellent thermal stability as well as mechanical properties due to excellent compatibility and processability with a polyvinyl chloride.
