Abstract
The use of surfactants in addition to proteolytic enzymes and other protein removing agents such as urea is a common practice in acquiring deproteinised natural rubber latex. In the present work sodium dodecyl sulphate and a hydrophobically modified polyfructose surfactant were used and compared in urea-deproteinisation of natural rubber latex. The resulting deproteinised NR latex were evaluated for their mechanical stability protein content nitrogen content swelling index tensile strength and surface morphology. The results showed that the mechanical stability surface morphology and mechanical properties after aging improved when both sodium dodecyl sulphate and hydrophobically modified polyfructose surfactants were used together. Furthermore the combination of both surfactants also reduced the extractable protein content nitrogen content and weight swelling index of the urea deproteinised latex.
