Melt agglomeration with hydrophobic meltable binders in high shear mixer

Melt agglomeration is an ideal model to elucidate the mechanism of agglomerate formation and growth as the interpretation of agglomeration outcome is not complicated by the evaporation of binding liquid. Although a substantial amount of work has been carried out on melt agglomeration process in high shear mixer using hydrophilic meltable binders such as polyethylene glycols, the findings are not fully applicable to hydrophobic meltable binders due to varying physicochemical properties of the latter than those of the former. The agglomerative capabilities of hydrophobic meltable binders remain not fully understood. The present project centers on the elucidation of the physicochemical properties of the hydrophobic meltable binders, in association with their agglomerative capabilities in melt agglomeration process in high shear mixer, involving the use of additives and various meltable binders. The study concludes that the melt agglomeration behaviour is predominantly dependent on the viscosity and surface tension of the binding liquid
