Polychlorinated terphenyl

Source: Wikipedia, the free encyclopedia.
General chemical structure of polychlorinated triphenyls where 0≤x≤5 and 0≤y≤4 and 0≤z≤5

Polychlorinated terphenyls (PCTs) are a group of

heat stability, and high resistance to alkalies and strong acids.[1]
They are non-flammable and insoluble in water.

Typically produced and used as mixtures with varying degrees of

lubricating oils, and as flame retardants.[1][2] Their production and use has been largely phased out due to environmental and safety concerns.[2]

International trade in PCTs is regulated by the Rotterdam Convention.
