Mooney Viscosity The Mooney Viscosity test is the most popular test method for characterizing polymers and uncured rubber materials. As defined by international standards, the sample material is preheated for a defined period in a closed die cavity, then 48. sheared by the embedded rotor at a constant rate. The Mooney Viscosity is recorded To that end, we investigated Mooney torque relaxation. The Mooney viscometer is an inexpensive instrument (cost and maintenance) that is easy to use and, above all, available in the great majority of factories producing natural rubber.

Abstract The direct near‐infrared spectroscopic reflectance measurements of prevulcanized natural rubber (brown crepe) was employed for determination of its Mooney viscosity. NIR reflectance spectra were obtained for a total of 100 samples whose Mooney viscosity (VM in the range 68–95 units) have been determined by the standard reference .
5. The maximum test time: Mooney: 10min; Scorch: 120min (modification time during testing) 6. Mooney value of measuring range: 0 to 200 7. Mooney value resolution: 0.1 Mooney value 8. Mooney value measurement accuracy: ± 0.5 Mooney value 9. Calibrate accuracy: 100±0.5 Mooney value 10. Rotor speed: 2 ± 0.02r/min 11. Traditional data-driven empirical models for online prediction of the Mooney viscosity have not utilized the information hidden in lots of unlabeled data (e.g., process input variables during each mixing batch). A simple semi-supervised nonlinear soft sensor method for the Mooney viscosity prediction is developed.Superior Die Cooling and Temperature Stability – Thanks to low mass dies and proprietary digital temperature control, Premier MV delivers excellent temperature stability and a 45% reduction in die cooling time compared to previous models.
