EFFECT OF DATE SEED POWDER FILLER ON PROPERTIES OF HIGH-DENSITY POLYETHYLENE

📄 Project Abstract

High-density polyethylene composites of date seed powder were prepared at filler loadings of 0 to 40wt%. The particle sizes of the date seed powder investigated were 72, 125, 150 and 180m. Calcium carbonate was used as a reference filler. The high- density polyethylene composites were prepared in a two-roll mill machine and the resulting composites were extruded as sheets. Mechanical, thermal, morphological and physical properties of the composites were determined. Results showed outstanding mechanical performance with the date seed powder. Impact strength, increased from 0.65 to 1.35J/m, flexural strength increased from 28 to 31MPa, hardness property increased from 67 to 74 J/m, tensile strength increased from 10 to 18J/m, and the tensile modulus also increased. These properties increased with increase in filler loading and decreased as the filler particle size were increased. However, the elongation at break of the composites was observed to decrease from 250 to 180 with increase in ...
