Standard Test Methods for Rubber Property—Processability of Emulsion SBR (Styrene-Butadiene Rubber) With the Mooney Viscometer (Delta Mooney)

Importancia y uso:

5.1 These empirical tests have been found to be suitable for ranking a series of unpigmented emulsion SBR in order of processability. They may also be used for comparing a production lot with a standard of known processability characteristics. The difference between Mooney viscosities at two specified times will rank those emulsion SBR polymers that differ appreciably in this property according to their processability. The actual values obtained for a given polymer depend on whether or not the sample was massed, and may vary between laboratories or with the type of machine used, and with the specified times at which Mooney viscosity values were taken.
