Abstract
The particle size distribution of a first fly ash is compared to an ideal particle size distribution that was empirically developed to provide a resin melt with a lower viscosity as more fly ash is added. A second fly ash material is similarly compared to the ideal curve and then is blended or optimized to provide an optimum filler for use with a suitable resin or similar material. The blended optimum filler is combined with a resin, an acid scavenger and an anti-oxidant to form a master batch which is available for mixing with other resins to form a material that is processed into a final product. Additional additives may be added for, among other things, foaming and coloration.
