Chlorendic Anhydride


Chlorendic anhydride is a reactive chemical intermediate used primarily in the preparation of flame-retardant polyester resins and plasticizers. It is also used as chemical intermediates in the manufacture of anti-corrosive (unsaturated) polyester resins with special applications in electronicsl industry, panelling, engineering, plastics and paints. A major application is in fibreglass-reinforced resins (composites) for process equipment in the chemical industry.
