increased capacity for its Eastman 168 general purpose non-phthalate DOTP plasticizer by 60% following the retrofit of the former Sterling Chemicals plant in Texas, which the company acquired last year. “This additional capacity will allow us to serve the growing demand for non-phthalate plasticizers such as Eastman 168 around the globe,” says Heidi Barnes, business director of

Eastman’s performance chemicals and intermediates segment oxo and plasticizers. Last year, Eastman also said it was to discontinue
production of its DEP and DBP low phthalate plasticizers, both of which would have required REACH authorisation for the European market. While not linking the decision to the REACH authorisation requirement, the company said at the time it had alternative fast-fusing, high solvating
