  • Patent number: 9505907
    Abstract: An ester composition including terephthalate compounds substituted with a non-hybrid and non-branched alkyl group, a hybrid and branched alkyl group, and a non-hybrid and branched alkyl group, respectively by 0.5 wt % to 9.5 wt %, by 14.5 wt % to 43.8 wt %, and 46.7 wt % to 85 wt % based on the total weight of the ester composition, a method of preparing the same, and a resin composition including the same are provided. The ester composition has a short absorption time with respect to the resin and short fusion time and improves the processability of the resin composition. In addition, good physical properties may be provided when manufacturing a sheet and a compound such as a cable, an interior of a car, a film, a sheet, a tube, a wallpaper, a toy, a flooring material, and the like.

  • Publication number: 20070027240
    Abstract: The present invention relates to a diethylene glycol ester based plasticizer composition comprising at least two diethylene glycol ester compounds. The diethylene glycol ester based plasticizer composition of the present invention offers superior tensile strength, elongation, transfer resistance, hardness, transparency, adhesivity, and compatibility with resin, when used for a plasticizer of a polyvinyl chloride resin, without releasing environmental hormones. Thus, it can be used for a polyvinyl chloride resin of a warp film.
