Abstract
The present invention relates to a plasticizer composition, a resin composition and methods for preparing thereof, and, by improving poor physical properties having been caused by structural limitation, provides a plasticizer capable of improving physical properties such as plasticizing efficiency, a migration property, tensile strength, an elongation rate, stress migration and light resistance required for sheet formularization when used as a plasticizer of a resin composition, and a resin composition comprising the same.
Claims17
A plasticizer composition comprising:
- a mixture of three kinds of terephthalate-based materials;
- and
- epoxidized oil,
- wherein the mixture of three kinds is a first mixture of di(2-ethylhexyl) terephthalate, butyl(2-ethylhexyl) terephthalate and dibutyl terephthalate;
- a second mixture of diisononyl terephthalate, butylisononyl terephthalate and dibutyl terephthalate;
- or a third mixture of di(2-ethylhexyl) terephthalate, (2-ethylhexyl)isononyl terephthalate and diisononyl terephthalate, and
- wherein the epoxidized oil is included in 20 wt % or greater with respect to the total amount of the plasticizer composition.
