Hexachlorocyclopentadiene

Versatile intermediate for multiple end-uses

Hexachlorocyclopentadiene (Hex) is an organochlorine compound that is used in the production of flame retardants, transport applications and pesticides. Hex is a highly toxic and corrosive material and as such is managed under a strict Product Stewardship Program. Potential users must go through a detailed review and education on product usage, storage, and waste handling and disposal.

Hex is used as the key raw material in Chlorendic Anhydride, a flame retardant used for its flame retardance and corrosion resistance. Hex is also used to produce PyroVex® SG, a flame retardant used in housing materials and wire and cable. A specialized use for Hex is in resins for transport vehicles to adhere rubber to metal substrates. It is also used in the production of a pesticide, endosulfan, which is applied on cotton, fruits and vegetables to combat a broad spectrum of insects and support the production of clothing and food supplies.
