Pipe covering and block

In July 1956, Asbestos, the industry's trade journal, reported Eagle-Picher vice president Glen J. Christner as saying that "the most important new additions" to its line of high-temperature insulating materials were Eagle-Picher HYLO Pipe Covering and Block.1 That report does not say who made the covering or whether it contained asbestos.1 An insurance company's 1981 list of asbestos products, compiled from other companies' answers in lawsuits, says Owens-Corning made the Hylo pipe covering and block and Eagle-Picher sold it under its own name; the list gives it as made from 1960 to 1972.2

Hylo Cement

In sworn answers given in a lawsuit in 1970, Eagle-Picher listed Hylo Cement as first made in 1963, and described it as "a dry, bulk cement composed of Eagle-Picher granulated mineral wool and diatomaceous earth thoroughly blended with suitable binding, rust inhibitive, and plasticizing ingredients."3 It listed asbestos among the ingredients, with bentonite clay, portland cement, plaster, sodium nitrate and a sudsing agent.3 The same answers say Eagle-Picher packaged Hylo Cement and sold it to contractors and to its distributors.3 The insurer's 1981 list gives Hylo cement as made from 1963 to 1974, with 5 in the column read as percent asbestos.2
