Abstract

Graphite filler reinforced polypropylene (PP) composites and talc filler reinforced PP composites were prepared by compression molding at 160⁰ C. Physical, optical and thermal properties were studied. Bulk density of test materials increased with the fillers content. The composites show good optical properties. Absorbance decreases with the increase of wavelength and the highest absorbance peak was found near about 200 nm. Their thermal stability has also been studied. The results reveal that the addition of 5 wt.% of graphite or talc improves the thermal stability. There is an initial DTA peak for both PP-graphite and PP-talc composites. Thermal analysis of PP-graphite filler composites and PP-talc filler composites show that thermal degradation of PP sheet starts ahead of composites. Dynamic mechanical analysis shows high elasticity and low energy loss both for 5% of PP-graphite and PP-talc composites. All of these results indicated that PP-graphite composites are better than the PP-talc composites.
