Filled polyolefin composites exhibit some improved properties obviously different from those of unfilled polymers. The present work focuses on the effect of reinforcing fillers on the properties of polyolefin composites. Their reinforcing effects were evaluated by comparison with those from silica, talc and clay. The mechanical, thermal and electrical properties of polyolefin composites with reinforcing fillers were investigated. It was found that polyolefin composites with reinforcing fillers exhibited better mechanical properties than that with unfilled composites. Silica in the group of reinforcing fillers could reduce mechanical properties such as tensile strength and modulus and thermal properties. Furthermore, it could lower electrical properties such as volume resistivity. On the other hand, composites filled with talc show best mechanical properties than any other reinforcing fillers. |
