It is interesting that the Mooney viscosity for one of the `bad' lots was very close to the Mooney viscosity for the `good' lot (ML1+4 of 93 vs 94). Table 11 gives a description of these three lots. Fig. 31 shows very good separation of the `good' vs the `bad' lots of natural rubber when comparing the uncured tan δ at high strain test conditions.
The influence of mixed rubber processing technology on Mooney viscosity and burning time was studied. The results showed that the Mooney viscosity of mixed rubber increased with the extension of . The results have shown that a change of 1 from the test temperature of 100 or 125 results in a 1.5-3% change in Mooney viscosity, depending on the type of rubber tested. 2.2.2.

Mooney viscosity Mooney viscosity for all formu-lations is shown in . Each Fig. 4 line indicates increasing Ca(OH) 2 levels at constant MgO. A neat linear relationship is observed for each one of the sets. With increas-ing total metal oxide content, the Mooney viscosity also increases. Slopes from these linear rela-tionships are plotted in . Fig. 5 Abstract The direct near‐infrared spectroscopic reflectance measurements of prevulcanized natural rubber (brown crepe) was employed for determination of its Mooney viscosity.
