Abstract
A plasticizer composition and a resin composition including the plasticizer composition. The resin composition addresses limitations associated with conventional plasticizers by improving various properties such as plasticization efficiency and mechanical properties including migration properties, volatile loss, tensile strength and elongation rate. The plasticizer composition is also capable of improving properties such as elongation retention and cold tolerance.
Claims17
A plasticizer composition comprising a cyclohexane 1,4-diester-based material comprising one or more cyclohexane 1,4-diesters, wherein each of two alkyl groups combined with two ester groups of the one or more cyclohexane 1,4-diester has a carbon number of 8 to 12;
- and a trimellitate-based material comprising a compound represented by the following Formula 1:
- wherein in Formula 1, R1 to R3 are each independently an alkyl group of 8 to 12 carbon atoms, and
- wherein a weight ratio of the cyclohexane 1,4-diester-based material to the trimellitate-based material is 90:10 to 10:90,
- the plasticizer composition further comprises two additional 1,4-diester cyclohexanes, each of which are different from the cyclohexane 1,4-diester having each of two alkyl groups having a carbon number of 8 to 12 combined with two ester groups,
- the plasticizer composition comprises 3.0 to 99.0 mol % of the cyclohexane 1,4-diester having each of two alkyl groups having a carbon number of 8 to 12 combined with two ester groups, and
- the plasticizer composition comprises 0.5 to 96.5 mol % of each of the two additional 1,4-diester cyclohexanes.
