Monsanto MONSANTO PHILIPPINES INC. Rufino Bldg., Ayala Ave. Commercial Confer P, O. Bon 59? Makati, Rijal, Philippines Tol.i 88-41-05 January 20, 1972 Philippine Pigment 5, Resin Corp. P. de Guzman St. pasay City Attention: The General- Manager Dear Sir: We are writing to advise you that, effective this date, Monsanto will no longer sell the Therminol FR series of heat transfer fluids. This important decision by Monsanto's management has been carefully considered. The Therininol FR series of fluids contain polychlorinated biphenyls (PCBs). Studies indicate PCBs may be accumulating in the environment. In some instances, PCBs have been found in food or in the food chain. An article by carl g. Gustafson of the Federal water Quality Administration appearing in "Environmental Science & Technology" and dealing with this subject is attached for your information. Because of Monsanto's concern over this problem, in the United States we Ijave previously discontinued sales of PCBs where the usage was in so-called "open systems" and previously where the usage would be in' food processing applications. We have now decided to withdraw all sales of Therminol FR heat transfer fluids world-wide. As a result of these efforts, many of our heat transfer fluid customers have switched frcm Therminol FR series fluids to other materials or systems. Our action in discontinuing sales for use in heat transfer systems has been taken because of the problems which may arise should there occur accidental leakage of PCBs from such systems. We believe this action is in the best interest of all our customers who have been using these materials in heat transfer applications. MOWS 095917
