MEMORANDUM TO: TRANSITE PIPE PRODUCT FILE (P-197) PROM: LKB DATE: June 26f 1990 RE: TYPE AND PERCENT OF FIBER IN TRANSITS CONDUIT AND KORDUCT . . Pursuant to a request from Mr. Yoeli of Gordon and Silber, I attempted to determine the fiber types and percentages in Conduit and Korduct. I first spoke with Tom Sadler, Manville Research and Development, on June 8, 1990, and he stated the following: Generally, Transite Conduit and Korduct contained between 10 to 12 percent asbestos fiber. Of that fiber blend, approximately ten percent was crocidolite for a total of one to one and one-half percent crocidolite in the total product. The remaining fiber was chrysotile. I subsequently spoke with Jack Cran, former Manville Transite Pipe Department employee, and he stated as follows: There was very little asbestos fiber used in the manufacture of Transite Conduit and Korduct--approximately ten percent chrysotile. No crocidolite was ever used. A conversation with Bill Streib, former Manville r&d employee, failed to resolve this dilemma. Therefore, with Mr. Streib's assistance and using the Transite Pipe fiber blend books and manufacturing specifications, I calculated the types and percent of fiber used in Transite Conduit and Korduct for all years in which I Was able to obtain both fiber blend formulations and furnish requirements. The results are attached, and are summarized as follows: 1. Total Fiber Range: 6.6% - 16.5% 2. Range of Blue Fiber: .02% - 4.45% 3. Range of Chrysotile: 5.4% - 15.12% 4. Range of Amosite (1953 and 1954): 4.0% - 4.7% I will manufacturing available. supplement this memorandum when additional specifications and furnish requirements become MTBH000891 EXH 2064-0015 Trademark details Search, protect and build your brand iPwish S,oread the Word Share!
