340 Cement was a Johns-Manville cement.1 An insurance company's 1981 list of asbestos products, compiled from other companies' answers in lawsuits, gives it as made from 1931 to 1969.1
A 1990 EPA notice that published what Manville reported gives figures only for a whole group of "Asbestos-Binder" cements, 340 among them, alongside Superex and 85% Magnesia.2 For that group it gives production years of 1930 to 1973, which are not the 1981 list's years for this cement, and says the cements contained 10 to 100% asbestos, with 0 to 30% each of diatomaceous earth, clay, portland cement and mineral wool.2 It describes the group as off-white to grey in color, packaged in cans or pails.2
