ESTER PLASTICIZER COMPOSITION

摘要

PURPOSE: An ester plasticizer composition with improved process ability is provided to improve absorption rate and melting time, thereby obtaining uniform foaming performance. CONSTITUTION: An ester plasticizer composition with improved process ability comprises a hybrid alkyl-substituted terephthalate-based compound and immiscible alkyl-substituted terephthalate compound. The hybrid alkyl-substituted terephthalate-based compound is formed by reacting alcohol and acid. The alcohol is the mixture of C3-4 non-branched primary alcohol and C8-10 branched primary alcohol. The immiscible alkyl-substituted terephthalate compound is represented by chemical formula 1. The mixing ratio of the hybrid alkyl-substituted terephthalate compound and the immiscible alkyl-substituted terephthalate compound is 50:50-10:90.
