G. C. Stefango to Don S. Wright on Discontinuing J-M Chrysotile in Kaylo (1961)

A one-page Owens-Corning Fiberglas letter of December 4, 1961, from G. C. Stefango to Don S. Wright in Toledo, headed "Chrysotile Asbestos," following J. W. Moore's telegram. Stefango explained that the decision to stop using J-M chrysotile came from a meeting with the sales people, who needed to reduce the chloride content of all Kaylo insulation to meet the demands of DuPont and Union Carbide. The chloride content of J-M's chrysotile was considerably higher than that of Lake Asbestos fiber. He wrote that "this matter must be handled tactfully" with J-M, and that Royce Ames fully agreed with the desire for dual sources.

Johns-Manville's legal department indexed the Motley 1,000 in 1984. Its index describes this document as follows:

G. C. Stefango (OCF) letter (very illegible) to Don S. Wright, et al. (OCF), 12/4/61, reacting to J. W. Moore's telegram (Motley Document #845). Stefango states that it has been necessary to take steps to reduce the chloride content of all Kaylo insulation to meet the demands of DuPont and Union Carbide. These customers are extremely important and have good reason for insisting upon material with a low chloride concentration. The chloride content of the J-M chrysotile asbestos is considerably higher than the chloride content of Lake Asbestos'. Stefango states that it has been decided to discontinue the use of J-M chrysotile asbestos. "This matter must be handled tactfully with J-M and I can assure you that Royce is completely behind us in the need for dual sources." Chris Pauley (current J-M industrial hygienist at Lompoc) believes that the reason OCF would not purchase a high chloride-containing fiber is because of product quality control problems and not because of health concerns. Although Chris is not positive about this.

Duplicate of Motley Document #846.
