    摘要: Increased bulk density of powdered flame retardants, flame retardant synergists and other powdered polymer additives substantially improves the processing, dispersibility, and properties of the processed polymer. Processing improvements include faster processing, more homogeneous additive dispersion throughout the polymer, less swell, and reduction or elimination of drool. Formed parts containing the increased bulk density flame retardant and flame retardant synergists are more consistent with respect to density, wall thickness, and more homogeneous and consistent flame retardancy. Physical properties such as flammability test performance and/or impact strength are also enhanced.
