Number One Plus (Keene)

Number One Plus was an insulating cement that later came under Keene.1,2 Keene's report published by the EPA in 1990 calls it "No. 1 Plus Cement/No. 1 Cement" and says it was produced from 1938 to 1971 by companies the report abbreviates as B–H, BEH and KBPC.2 It describes a dry mixture of spun mineral wool granules, bentonite clay binder, chrysotile asbestos fiber (7.5%) and other ingredients, which formed a thermal insulation capable of withstanding temperatures from 1,800° to 2,100 °F.2 For approximately 1 year around 1970, Keene says, a Military Formulation of No. 1 Plus Cement was manufactured.2 It says asbestos was removed from the product in 1971.2

An insurance company's 1981 list of asbestos products, compiled from other companies' answers in lawsuits, lists Number One Plus cement under Keene as made from 1938 to 1971, with Baldwin-Ehret-Hill in its note column and 7.5 in the column read as percent asbestos.1
