Dechlorane Plus

Dechlorane Plus is a flame retardant containing chlorine.

Chemical Formula: C₁₈H₁₂Cl₁₂

Other names: Dechlorane Plus, 1,6,7,8,9,14,15,16,17,17,18,18-Dodecachloropentacyclo(12.2.1.1$6,9!.0$2,13!.0$5,10!)octadec-7,15-diene

Layman's explanation: Dechlorane Plus is used as an additive in flame-retardants, this white crystalline, free-flowing solid that can be tailored to meet the most demanding flammability specifications and is currently the only chlorinated flame retardant on the market. This substance inhibits flaming drips and also reduces flam propagation to result in the production of lesser smoke. Dechlorane plus demonstrates UV stability to reduce discoloration and also exhibits thermal stability to allow for easier processing. It was introduced as a substitute for Dechlorane (also called Mirex, C10Cl12) by Hooker Chemical (now a part of Occidental Chemical Corporation and known as OxyChem) in the 1960s. It is still being used although there are concerns about its persistence in the environment as the compound was recently detected to accumulate in the Great Lakes (air, sediment, and fish). Major applications of DP are industrial polymers used for commercial electrical wires and cables, connectors used in computers, and plastic roofing material. Three types of DP are available (DP-515, 25, and 35). These products differ in their particle sizes, but they have the same chemical composition.
