摘要： A plasticizer composition which includes a lower non-hybrid-type cyclohexane triester, a lower hybrid-type cyclohexane triester, a higher hybrid-type cyclohexane triester, and a higher non-hybrid-type cyclohexane triester, wherein the alkyl groups of the cyclohexane triesters are a combination of C3-C6 alkyl groups and C7-C10 alkyl groups. When the plasticizer composition is applied to a resin, stress resistance and mechanical properties are maintained at an equivalent level or improved, migration properties, volatile loss characteristics, and plasticization efficiency are balanced, and light resistance and heat resistance are significantly improved.

摘要： The present invention relates to a plasticizer composition and a resin composition including the same. When the plasticizer composition is used as a plasticizer in the resin composition, the plasticizer composition may be environmentally friendly, may be improved in processability due to an enhanced absorption rate and enhanced plasticization efficiency, may reduce the total amount of the plasticizer to be applied due to improved physical properties such as migration and volatile loss, and may also have excellent mechanical properties due to improved tensile strength and an improved elongation rate as a plasticizer.
