Abstract

The mechanical properties of recycled High-Density Polyethylene (rHDPE) are inferior compared to non-recycled HDPE. To overcome this prob-lem, Calcium Carbonate (CaCO3) is added to improve the material’s mechanical properties. The temperature and injection pressure changes can affect the mate-rial’s mechanical properties. This research uses a factorial design methodology with two replications to investigate the interaction effect of the CaCO3 composi-tion, injection temperature, and injection pressure on recycled HDPE's tensile strength and hardness. The results showed that the interaction between the CaCO3 composition and temperature, the CaCO3 composition and pressure, and temper-ature and injection pressure increase the value of tensile strength. The interaction among the three independent variables at a high level has the most influence on tensile strength. The hardness value is influenced by the interaction between the CaCO3 composition and temperature, the CaCO3 composition and pressure, and temperature and injection pressure at all levels. The presence of CaCO3 has the most significant effect on the specimen’s hardness. However, the interaction with temperature and pressure reduces the effect of CaCO3 in increasing the hardness value.
