This Is an update on our position on the use of asbestos based friction materials in Airflex products. iX"" In essence, our position is the same as that originally, expressed in Bob Rosenow's Sales Department Letter #76-46 back ini-976,, -Although * -% ''a.;*.*' w there is a significant asbestos content in thesa materials, S;to the best of our knowledge, very little of this asbestos5is'liberated to the air in normal use of the clutch and/or brake; The vfery localized hot spots at the friction surface chemically changes'-the asbestos into other harmless minerals.
