Significance and Use
4.3 Carbon black is hygroscopic. The amount of moisture absorbed is related to the surface area of the black and to the relative humidity, ambient temperature, and time to which the material is exposed.
1.1 These test methods cover the determination of the heating loss of carbon black at 125°C. This heating loss consists primarily of moisture, but other volatile materials may also be lost. These test methods are not applicable to treated carbon blacks that contain added volatile materials, if moisture loss is to be measured.
