Abstract
Thermal analysis of the natural rubber Hevea brasiliensis latex (NRL) with different moisture content was characterised using differential scanning calorimeter. The analysis was done between -100C to 150C. The thermal characteristics investigated are the glass transition temperature Tg the boiling point of free-water Tf and bound-water Tb. Results showed that Tg for both dried concentrated rubber latex and dried NRL are similar i.e. -56.84C and-56.57C respectively while Tg for diluted NRL was not detected. The existence of moisture shifted the Tf in diluted NRL towards a higher temperature which was similar to the thermogram of de-ionised water.
