Extrusion and Evaluation of Saw Dust-Recovered HDPE Composite Bars

Abstract:

Wastes such as saw dust (Pinus Radiata) and milk bottles (High Density Polyethylene - HDPE) are available in abundance. HDPE bars and composite bars, consisting of different volume percentages (50%, 60% and 70%) of saw dust and recovered HDPE, were extruded using a co-rotating, conical, twin screw extruder with a slit-profile die and an innovative sizing-cooling box. The extruded bars were evaluated on their surface finish, shape conformance and materials distribution across the cross-section. Mechanical testing of the extruded bars was carried out using appropriate ASTM standards after they met the required quality ratings.
