Description

GNPGraystar’s ATH has a unique particle size distribution that provides the best possible combination of viscosity, flame, electrical, and molding properties that can be derived from an ATH filler. A closely controlled top size with a large super fine faction yields rapid dispersion in resin. Excellent mold flow and wet-out characteristics result in superior surface profile, minimal porosity, even pigmentation, and excellent filler and reinforcement distribution throughout the molded part.
