J. H. Kietzman (Johns-Manville) to F. H. Ancker on Draft Report 'Asbestiform Fillers' and Request for Permission to Use Calidria Data (1977)

A cover letter from John H. Kietzman of Johns-Manville to F. H. Ancker of Union Carbide enclosed a draft state-of-the-art report on asbestiform fillers for an American Chemical Society book on plastics additives. The letter asked for written permission to use data from Ancker's July 1974 Plastics Engineering article. The attached draft report (marked CONFIDENTIAL) compared chrysotile, talc and wollastonite in plastics, and ended with a section on environmental control and asbestos health risks.
