Hexachlorocyclopentadiene is the basis for a number of pesticides such as Chlorodane, Aldrin, Dieldrin, and Kepone. The production of some of these materials has been banned in many regions because of their carcinogenic properties and toxicity to wildlife. Hexachlorocyclopentadiene is also the raw material for chlorendic acid, which is used as a flame retardant (product information from Velsicol Chemical Corp.) for imsatimated polyester resins. 

The annual capacity of DCPD production for all grades in the United States is estimated to be in excess of 350 million pounds in 1999. The major US. producers are B. F. Goodrich Co., Equistar Chemicals (a joint venture of Lyondell Petrochemical, Milennium Chemicals, and Occidental Petroleiun Co.), Exxon Chemical Co., Phillips Petroleum Co., Shell Oil Co., Texmark Chemicals, and Velsicol Chemical Corp. The major consumptions of DCPD in the United States are in the production of hydrocarbon and imsaturated polyester resins (80%), ethylene-propylene terpolymers (10%), reaction injection molding (5%), and miscellaneous uses (5%). The last includes flame retardants, pesticides, antioxidants, and metallocene catalyst production. The demand for DCPD will grow in a rate of 4% per year in the next several years.
