Abstract
The preparation and characterization of Unsaturated Polyester Resin (UPR) filled recycled Expanded Polystyrene (EPS) composite systems were systematically investigated. Additives such as Alumina and Organic Nano-crystal (ONC) were added to the composite for infrared reflection enhancement. The effect of different weight percentage of additive on the thermo-physical properties, e.g. thermal conductivity and physical density were determined. The fabricated composite undergoes thermal analysis by using a hand-held thermal probe which yield thermal conductivity, thermal resistivity and heat capacity data for analysis. The results obtained from comparing the use of ONC additive against alumina addition in the composite system revealed and concluded that ONC could impart better heat insulation to the studied composite using a lower concentration. It can be inferred that this is might be due to alumina being a metal oxide, which are more heat conductive compared to ONC. Further studies on the material can be done to determine the actual mechanism of how ONC and Alumina enhances thermal insulation by reducing thermal conductivity and increasing heat capacity of the composite.
