PRODUCT OVERVIEW

DESCRIPTION

Phthalic anhydride is a white crystalline compound used primarily as a chemical intermediate in the production of various plasticizers, resins, and dyes. It is a cyclic anhydride of phthalic acid and is derived from the oxidation of naphthalene or o-xylene. Phthalic anhydride is commonly used in the production of polyester resins, which are used in the manufacture of fiberglass-reinforced plastics, automotive parts, and other products. It is also used in the production of phthalate esters, which are plasticizers used in the production of flexible PVC products such as wire and cable insulation, flooring, and medical tubing.
