Abstract:
1. A method of making a composition, comprising: providing chemical wood pulp fibers in the form of particles, thermoplastic polymer, and mineral oil to a first mixing device, wherein for every 100 weight percent of material provided to the first mixing device, the pulp fibers are 65 to 90 weight percent of the material and the mineral oil is 0.1 to 5 weight percent of the material, mixing the fiber, the polymer and the mineral oil in the first mixing device to form a fiber/polymer blend in which the substantially individual chemical wood pulp fibers are dispersed within the polymer, further mixing the fiber/polymer blend in a second mixing device, wherein the second mixing device uses split flow to disperse the fibers in the polymer, and thereafter forming the fiber/polymer blend into pellets.
