Abstract

Polymer blending is a process of combining two or more types of polymer in order to achieve the desired properties rather than developing new polymer. This study is conducted to characterize the thermal conductivity properties and tensile strength properties of polymer blend consisting of polypropylene and polycarbonate. Polypropylene-grafted-maleic anhydride was chosen as compatibilizer to improve the miscibility of the blend. Eight different weight composition ratios of the blend are designed which are 90/5/5, 85/10/5, 75/20/5, 65/30/5, 90/10/0, 80/20/0, 70/30/0 and 60/40/0 (in PP/PC/PP-g-MA respectively). The glass transitional and melting temperatures of PP, PC, and PP-g-MA were obtained by differential scanning calorimetry (DSC) and the values were consistent with literature. Then, the polymers will be compounded in twin screw extruder. Samples for thermal conductivity test are fabricated by compression moulding. Lab testing will be done on the samples to determine the value of thermal conductivity of each formulation by using ASTM E1225 -04 Standard Test Method for Thermal Conductivity of Solids by Means of the Guarded-Comparative-Longitudinal Heat Flow Technique. Samples for tensile strength test are prepared by injection molding machine and the testing is done according to ASTM 0638-10 Standard Test Method for Tensile Properties of Plastics.
