Abstract
One of the most serious problems encountered in poly(vinyl chloride) (PVC) processing is due to low thermal stability of the PVC. The purpose of the study was to determine the effect of LDPE and flame retardant on to the electrical and thermal nanocomposites properties The nanocomposites were prepared using a laboplastomill with (15; 20; 25 and 30 phr) LDPE and (30 and 35 phr) flame retardant at 215 ºC and 50 rpm rotor speed. The thermal properties of nanocomposite was evaluated by TGA/DTA and DSC, electrical properties was evaluated by volume resistivity. Thermal analysis results revealed that decomposition of nanocomposites occured at 280 ºC. DSC results show that crystalisation temperatur (Tc) at 250 ºC, melting temperature (Tm) at 260 ºC and glass temperature (Tg) at 60 ºC. The IR spectra of nanocomposites showed that there was absorption at 1579 cm-1 formed polyene (C=C). The electrical testing of nanocomposites fullfill the quality requirements of SNI 04-6504-2001 Lampu swaballast untuk pelayanan umum-persyaratan keselamatan ≥ 4 MΩ.
Keywords: nanocomposites, PVC, LDPE, thermal, electrical.
