Abstract
A preliminary study was conducted to investigate the effect of aluminum hydroxide (ATH) as a deproteinizing agent in commercial natural rubber latex (NRL) onto the physicochemical properties of the NRL. The loading of ATH in NRL was varied at 0.05 parts per hundred rubbers (phr), 0.10 phr, 0.15 phr and 0.20 phr. The optimum amount of ATH in NRL was determined from pH value, mechanical strength time (MST), protein content and Fourier Transform Infrared spectroscopy. The addition of ATH in NRL reduced the protein content of NRL (3.52%) to the lowest (1.19%) at 0.15 phr ATH. Protein-aluminate complex was detected from the FTIR spectra through peak at 3498 cm-1, referred to as C-N-H functional group.
