Compounding of cellulose fibers with polypropylene: Effect of fiber treatment on dispersion in the polymer matirx

Abstract

Abstract The compounding of Kraft pulp with polypropylene was stuided using a laboratory higheshear roller blender. Dipsersion was characterized by measuring the size and number of agglomerates in a thin compression‐moldled sheet. The effects of parameters such as surface treatment and mixing conditions were investigated. It is shown that with a suitable treatment, better dispersion of fibers can be achieved.
