Abstract
A method of making a polymeric compound with nanofiller of a predetermined grade. The method includes the steps of providing a base grade of the polymeric material, and mixing a nanofiller concentrate material with the base grade polymeric material in a ratio sufficient to render the predetermined grade of filled polymeric compound, the ratio being nanofiller concentrate material to base grade polymeric material. A method for making the nanofiller concentrate material includes the steps of mixing a high flow carrier resin and a nanofiller to form a mixture, extruding the mixture, and pelletizing the extruded mixture. The mixture may advantageously include colorants, such as pigments or dyes.
