The present invention is characterized by containing dihexyl isophthalate and di(2-ethylhexyl)terephthalate wherein the dihexyl isophthalate bears an alkyl group derived from a hexyl alcohol isomer mixture. When the plasticizer is applied to a resin, the resin can maintain the plasticizing efficiency, migration loss, and loss on heating at equivalent levels or greater and can improve the tensile strength and elongation thereof. La présente invention est caractérisée en ce qu'elle contient de l'isophtalate de dihexyle et du di(2-éthylhexyl)téréphtalate, l'isophtalate de dihexyle contenant un groupe alkyle dérivé d'un mélange isomérique d'alcool hexylique. Lorsque le plastifiant est appliqué à une résine, la résine peut maintenir l'efficacité de plastification, la perte de migration et la perte à la chaleur à des niveaux équivalents ou supérieurs et la résistance à la traction et l'allongement de celle-ci peuvent être améliorés. 본 발명은 다이헥실 이소프탈레이트 및 다이(2-에틸헥실) 테레프탈레이트를 포함하며, 상기 다이헥실 이소프탈레이트가 헥실 알코올 이성질체 혼합물로부터 유래되는 알킬기를 가지는 것을 특징으로 한다. 이를 수지에 적용할 경우, 가소화 효율, 이행손실 및 가열감량은 동등 이상의 수준을 유지할 수 있고, 인장강도와 신율을 개선할 수 있다.
