9 3 GASKETS A chemical manufacturer in Manchester, making sulphuric acid, found that the packing rings joining two pipes in his plant would not stand up to the highly corrosive action of the boiling acid. As a result; the joint leaked and pro- duction had to be interrupted every two weeks whilst new packing rings were fitted: Having tried different types of jointing material without success, the manufacturer asked ICI if they could offer a satisfactory alternative. The prob- lem was referred to ICI Plastics Division, who at that time were engaged in the experimental manufacture of "Fluon ~a fluorine organic compound which is completely resist- ant to acids, alkalis and solvents. A number of 'Fluon rings made specially by the Division S technical service department were supplied and fitted to the joint. These proved entirely satisfactory. The "Fluon" rings and the joint are still intact today after more than four years of constant usel Fluon in the form of valve seats, tape, packings and gaskets made by trade fabricators, is now used by the chemical industry in the manufacture and storage of corrosive liquids: ICI IMPERIAL CHEMICAL INDUSTRIES (NZ) LTD.
