Comparisons of some properties of deproteinised natural rubber vulcanisates and observations on dynamic load analysis

Two types of deproteinised natural rubber,one having an anionic surfactant (dpnr-a) and the other a fructan based surfactant (dpnr-b) are introduced in the present study and compared to commercial deproteinised natural rubber (dpnr-c) and conventional standard malaysian rubber (smr). comparisons were made in relation to their curing behaviour,physical properties,crosslink density and dynamic load analysis. the results revealed that the characteristics and behaviour of dpnr were mostly similar with those of the smr. however,certain properties such as the dynamic properties were shown to be better than those of smr. the best damping behaviour was observed in dpnr which incorporated anionic surfactant during its processing. from the dynamic analysis results,dpnr is shown to be a potential material for rubber engineering components and in particular for automotive applications.
