Characterization the rheology behavior of modified skim rubber

Test of the rheology behavior for modified skim rubber (MSR) were carried out with rubber processing analyzer (RPA), and mooney viscosity were carried out with Mooney Viscometer. The results showed that mooney viscosity of MSR is lower than skim rubber, and it is higher than SCR-5 (Chinese Standard Rubber-5). The complex viscosity (n*) and the stress relaxation have same results with mooney viscosity, that MSR's is higher than SCR-5 and lower than skim rubber. The elastic torque (S') is increased with the frequency rising, and the S' of MSR is in the middle of the all samples.
