• heat resistance to prevent thermal decomposition of the packing due to elevated shaft speeds and high temperature fluids; a chemical resistance to prevent deterioration of the packing due to contact with caustic and potentially explosive fluids; • durability to provide long lasting control of fluid flow; and, • low cost (ICF l986a). B. Producers and Importers of Asbestos Packing Table 3 lists the fiber consumption and quantity of packings produced in 1985. (Raymark Corporation refused to provide production and fiber consumption data for 1985, but was a producer in 1981 and so was assumed to have continued production of asbestos packing.) The values for domestic asbestos fiber consumption in the production of asbestos packings and the total amount of asbestos packings produced have been changed to account for the output of Raymark Corporation using the methodology described in Appendix A to this RIA. The adjusted values are 2.1 tons and 3 tons for fiber consumption and packings production, respectively (ICF 1986a). The secondary processors of asbestos packings in 1983 include: FMC Corporation in Houston, Texas and WKM Division of ACF Industries, Inc. in Missouri City, Texas. While WKM Division imported its asbestos mixture, FMC Corporation used domestic supplies in 1985. These companies received packings and further processed them in order to meet specifications of their customers (ICF l986a). C. Trends Three manufacturers, Johns-Manville Corporation (now Manville Sales Corporation) in Manville, New Jersey, Rockwell International in Pittsburgh, Pennsylvania, and John-Crane Houdaille (now Crane Packing) in Morton Grove, Illionois, ceased production of asbestos packings between 1981 and 1985. -9-
