Significance and Use | ||||||||
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. |

1. Scope | ||||||||
1.1 These test methods explain the use of the shearing disk viscometer to obtain an indication of the processability of non-pigmented emulsion styrene-butadiene rubbers (SBR). They may also be used to separate those polymers that are easy to process from those that are difficult to process within a group of polymers of the same type. 1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. 1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. |
