  • Stearic Acid-Treated Calcium Carbonate Compositions Having Low or No Detectable Free Stearic Acid and Related Methods
    Publication number: 20160152802
    Abstract: A method for treating calcium carbonate includes combining calcium carbonate with an amount of stearic acid and an amount of water to form a mixture, the amount of water being at least about 0.1% by weight relative to the total weight. The method further includes blending the mixture to form a stearic acid-treated calcium carbonate composition.
    Type: Application

  • Method for manufacturing cellulose fiber reinforced composites having reduced discoloration and improved dispersion
    Publication number: 20040140592
    Abstract: The present invention provides composites prepared from melt blending compositions that generally include cellulosic pulp fibers having an alpha-cellulose purity of greater than 80% by weight, at least one water soluble binder, at least one lubricant, at least one compatibilizer, and at least one matrix polymer. The present invention further provides advantageous temperature profiles and feeding arrangements to be used in conjunction with the melt blending of such composites. The composites of the present invention exhibit reduced discoloration and improved fiber dispersion.
