85 Magnesia (Fibreboard)

85 Magnesia was Fibreboard's magnesia insulation, made as pipe covering, block and cement.1,2 In sworn answers in two lawsuits, given in 1969 and 1970, Fibreboard listed "85% Magnesia (Precision Molded) Pipe Covering, Block, Cement" and said these products contained 85% basic magnesium carbonate with 15% asbestos.1,3 Fibreboard's report published by the EPA in 1990 gives about 85% or more basic magnesium carbonate and 15% or less asbestos, and describes the insulation as white.2

The documents give different starting years.1,2,4 The 1969 and 1970 answers say the products were made from 1941 until 1966.1,3 The 1990 report says from about 1928 to 1966.2 In 1968 the plaintiff in another lawsuit, Claude J. Tomplait, wrote in sworn answers to Fibreboard's questions, "I note from your answers to interrogatories that you began manufacturing 85% magnesium in 1925", but the Fibreboard answers he refers to are not in the file.4

The 1970 answers say the products on Fibreboard's list, this one among them, were sold mainly in the West and Midwest for new construction of refineries, petrochemical plants and power plants.3 An insurance company's 1981 list of asbestos products, compiled from other companies' answers in lawsuits, gives 85 Magnesia pipe covering, block and cement under Fibreboard Corporation, with 15 in the column read as percent asbestos, and marks the name as a generic term used by several makers.5
