Abstract

In this project, our aim is to enhance the thermal properties (melting point, crystallization, thermal stability and thermal conductivity) of Polypropylene polymer (PP) by mixing with metallic powder (copper). Polypropylene (PP), was mixed with different percentage of copper powder separately by using the polymer extruder facilities in RCYCI research center. The metallic powder percentages were of the total mass of polymer and compared with the pure PP. and the test was conducted at different voltages. A linear heat conduction machine was used to test the samples with different voltage 9 volt, 11 volt, 13 volt, 15 volt. Also, Differential scanning calorimetry (DSC), and thermal gravimetric analysis (TGA) were used. From heat linear conduction test, we proved that the thermal conductivity of mixed polypropylene polymer has been improved. The pure polymer was considered as reference so the thermal conductivity at 15 volts increased by. From DSC the maximum melting point was 161.39 C at 6% and the heat flow was approximately 18.2 mw. and minimum melting point was 160.19 C at pure Polypropylene and heat flow was 17.52 .                The highest TGA stability was for 10% (509 C) which is the point loss its properties at the maximum temperature. The crystallization point at 10% was 161.41 C which is the maximum among the other percentage.
