Patents Assigned to Eastman Chemical Company
  • Publication number: 20240191059
    Abstract: The present invention provides a non-phthalate, highly sustainable plasticizer, with performance comparable to or better than the existing orthophthalate market leader (DINP) and non-phthalate market leader (DOTP) at a lower cost position. The novel plasticizers are terephthalate ester and epoxidized oil compositions and dibenzoate ester and epoxidized oil compositions. The novel plasticizer compositions are produced by blending a fast fusing terephthalate diester or dibenzoate ester with an epoxidized oil. The presence of the terephthalate diester or the dibenzoate ester in the blend imparts better physical properties and performance properties over the ester or epoxidized oil components alone.
