Dicyclopentadiene (DCPD) is a man-made substance produced as a by-product of the manufacture of ethylene and is a colourless, waxy, flammable solid or liquid, with a camphor-like odour. As dicyclopentadiene enters the air, it breaks down quickly into simpler, less-toxic chemicals. However, it can stay unchanged for a long time in soil and in water.
Dicyclopentadiene is used in many products, ranging from high quality optical lenses through to flame retardants for plastics and hot melt adhesives. As a chemical intermediate it is used in insecticides, as a hardener and dryer in linseed and soybean oil, and in the production of EPDM (ethylene propylene diene monomer) elastomers, metallocenes, resins, varnishes, and paints. DCPD-containing products are also used in the production of hydrocarbon resins and unsaturated polyester resins.
