| abstract |
The present invention relates to a plasticizer composition, which includes a terephthalate-based material in which alkyl groups bonded to a diester group have a weight average carbon number of greater than 7 and less than 9; and a monobenzoate-based material including one or more compounds represented by Chemical Formula 1, wherein a weight ratio of the terephthalate-based material and the monobenzoate-based material is 99:1 to 1:99. Such a plasticizer composition is environmentally friendly, and can also improve properties such as tensile strength, elongation rate, hardness, and the like and migration resistance to stress so as to be suitable for use. |
