Aluminum diethylphosphinate or Depal is a phosphorus-containing flame retardant which is manufactured by Clariant in Knapsack under the trade name Exolit OP .
The compound is used as an additive in plastics and works by releasing phosphorus-containing products when heated. The degradation products trap the hydrogen and hydroxyl radicals in the flame zone and thus lead to flame poisoning. The flame retardant effect of aluminum diethyl phosphinate is therefore of a chemical nature.
The few studies available indicate a low toxicity of the compound.
