Chemical Properties & Typical Applications
TO ENHANCE IMPROVED CLARITY, FLEXIBILITY AND STRENGTH IN POLYESTERS. DMIP delivers strength, clarity, flexibility, good solvency and plasticization of polyesters. It is increasingly being utilized for fibers, films and optical lens applications. It is used as a plasticizer or as an intermediate to increase the molecular weight of polyesters, contributing to enhanced mechanical and optical properties such as transparency. It also contributes to heat resistance and increased adhesion in PET & PEN type polyester films and laminating resins. It is increasingly used to the applications include textile film, metal, paper processing, paints and specialty inks.
It is used primarily to improve the clarity and strenghth of PET carbonated drink bottles.
Another significant applicant area is in optical resin, Thermoplastic elastomer, engineering plastics
One of the principal uses of Dimethyl Isophthalate is as an intermediate in the synthesis of polyesters. In order to obtain the structural strength needed in fibers and films, the polyester must be of high molecular weight. The most efficient route to these high molecular weights is through transesterification of methyl ester with a glycol. A specially purified methyl ester is needed in this application.
