The use of wood and other cellulosic fillers have been used extensively to fill both thermoset and thermoplastic compounds for decades. Recent advances in compounding technology and further research into this area have resulted in the development of injection molding and profile extrusion grades of thermoplastic compounds which provide many benefits to a wide variety of end-users. However the use of these types of fillers, like other fillers, can cause a number of compounding and processing problems associated with the dispersion of the filler and flow characteristics of the resulting mixed composite. Common deficiencies include surface mottling and fracture, poor flow characteristics and compounding problems due to low temperature mixing requirements.
In this presentation we will discuss the use of chemical process additives, viscosity modifiers and dispersion enhancers in wood flour-filled polypropylene composites. It is our goal to show improvements in flow, surface appearance and physical properties at specific levels of filler loading and further that the use of these types of additives may allow for higher levels of filler loading without sacrificing processability, performance properties or surface appearance.
