Fundamentals of Carbon Black - Modern Dispersions

Color properties of carbon black are measured using colorimeters and have values of L, a*, b*. Typically, carbon black is compounded into the host plastic matrix at concentrations near 1-2% and then the color values are measured on a molded plack specimen. The L value (white = 100, black = 0) measures color density, the b* value is indicative ...
