AN ATTEMPT FOR CORRELATION BETWEEN MOONEY VISCOSITY AND RHEOLOGICAL PROPERTIES OF FILLED RUBBER COMPOUNDS

Open publisher page 7 citations

Abstract

For the characterization of rubber compounds from the point of view of their processing capability in the rubber industry is widely used a technological indicator – the Mooney viscosity. The Mooney viscosity obtained gives information just for one point of the flow curve of the respective rubber or rubber compound. This is the reason that no full rheological characteristics of the elastomeric material are obtained. The aim of this study is to find a correlation between the Mooney viscosity and the torque on a Plasticorder for rubber compounds. A correlation was settled between the Mooney viscosity ML and the torque M B and the corresponding equations for this dependency were derived for rubber compounds based on SBR (styrene-butadiene rubber) containing different types of carbon black and for compounds with one and the same type of carbon black, but of different level of filling.
