Transite Core Plate was a Johns-Manville asbestos-cement board.1,2 In sworn answers in two lawsuits, in 1969 and 1970, J-M listed it among its asbestos cement sheets as a "smoothly sanded tray of asbestos and cement for holding cores during baking or drying."1,3
An insurance company's 1981 list of asbestos products, compiled from other companies' answers in lawsuits, gives Transite Core Plate, listed as board, as made from 1938 to 1981; 1981 was the list's own year, so the end date may mean it was still being made.2 A 1990 EPA notice that published what Manville reported gives 1938 to 1978, but as one date range for a group of asbestos-cement sheets and boards that includes Transite Core Plate, along with Marine Veneer, Pallite and Dekeran Transite Board.4
For that group the notice gives a single set of figures: asbestos fiber, 5 to 50%; portland cement, 40 to 45%; and silica, 25 to 30%.4
