Books about 85% Magnesia, an Asbestos insulation product

85% Magnesia was an insulation product that contained up to 15% asbestos fibers. 85% Magnesia was sold as pipe covering, blocks, lagging, and cement. It was used as pipe covering on U.S. Navy ships to cover steam pipes during the 1930s, through WWII, and possibly later.

Companies that sold or distributed it include Keasbey and Mattison Company, Armstrong Cork Company, Ehret Magnesia Manufacturing Co, Johns-Manville and The Philip Carey Manufacturing Company.

Durant Insulated Pipe was one brand that was used to insulate underground pipes.

85% Magnesia is a potential health hazard because of its asbestos content. Exposure risk is particularly high when 85% Magnesia has to be replaced or repaired during maintenance work, ship overhaul, construction work, etc.
