Pengaruh filler PCC (precipitated calcium carbonate) terhadap sifat mekanik, elektrik, termal dan morfologi dari komposit HDPE/PCC

The purpose of this research was to know the effect of precipitated calcium carbonate (PCC) on morphology and quality of the HDPE g-MAH with PCC as filler. The process of HDPE g-MAH /PCC composites with a rheomix 3000 Haake at 180 º C and 50 rpm of rotor speed for 10 minutes. The composition of HDPE and additives are set constant, and PCC content was varied 10, 15 , 20, 30,40 and 50 phr (per hundred resin). The results of scanning electron microscopy showed that composite HDPE-g-MAH dan 30 phr of PCC was compatibel. Analysis functional group on composites with Fourier Transform Infra Red (FTIR) indicated wave band on 3449,61 cm-1, 2921 cm-1, 1707,21 cm-1, 1485 cm-1 dan 722,03 cm-1. The test results of the electrical properties (insulation resistance : ? 4 MΩ and electric resistance : no holed), and thermal properties (sparks : no flame and tissue not burned) indicate that all of the composite HDPE-g- MAH/PCC fullfill SNI 04-6504-2001, except resistance to heat.
