Dekeran (Johns-Manville)

Dekeran was a Johns-Manville board.1 An insurance company's 1981 list of asbestos products, compiled from other companies' answers in lawsuits, gives it as made from 1970 to 1975.1

A 1990 EPA notice that published what Manville reported names "Dekeran Transite Board" in a group of asbestos cement sheets, with Marine Veneer, Pallite and Transite Core Plate, and gives its figures only for the group as a whole.2 For that group it says production ran from 1938 to 1978, and the sheets contained 5 to 50% asbestos fiber, with 40 to 45% portland cement and 25 to 30% silica.2 It describes the group as asbestos-cement sheet or board.2
