PRODUCT: Chlorendic Anhydride

I.Specification

Chlorendic anhydride is reactive chemical intermediates used primarily in the preparation of flame-retardant polyester resins and plasticizers under free water conditions. It is among the most reactive flame retardants in use. It is also used as chemical intermediates in the manufacture of corrosion-resistant (unsaturated) polyester resins with special applications in electrical systems, panelling, engineering, plastics and paints (Makhoulf, 1982). A major market is in fibreglass-reinforced resins for process equipment in the chemical industry.
