Thermal and impact properties of HDPE/ Sayong clay / Muhammad Noor Afiq Mohd Yazed ... [et al.]

This study shows the effect of clay apply on the thermal and impact strength properties of high-density polyethylene (HDPE). For this purpose, clay reinforced with HOPE composites that being prepared through a melt mixing by using a compounder system. HOPE then undergo Izod Impact strength test in temperature range of 25"C. The result showed that the accumulated clay particles that arise in addition of clay caused the decreased in impact strength. To study the melting point and crystallization behaviour of clay reinforced with HDPE, DSC were conducted on the samples at the temperature of 50°C to 180 °C and at the rate of l 0°C/min. The result showed that the more the clay added to HDPE, the higher the melting point of the mixture. The crystallization behaviour of HDPE affected with addition of Sayong clay in which make the composite easily become crystal form even at high temperature.
