WebDicyclopentadiene (DCPD) is a colorless, waxy, flammable solid or liquid, with a camphor-like odor. The odor threshold is 0.005 ppm, and becomes irritatingat 0.048 ppm. The flash point for dicyclopentadiene is 41°C (106 °F). The boiling and freezing points of dicyclopentadieneare 55 °C (132 °F) and -25 °C (-13 °F), respectively. Dicyclopentadiene, abbreviated DCPD, is a chemical compound with formula C10H12. At room temperature, it is a white brittle wax, although lower purity samples can be straw coloured liquids. The pure material smells somewhat of soy wax or camphor, with less pure samples possessing a stronger acrid odor. Its energy density is 10,975 Wh/l. Dicyclopentadiene is a co-produced in large …
