sulfur dispersion quantitative analysis in elastomeric tire sulfur dispersion quantitative analysis in elastomeric tire
abstract. good dispersion of compounded ingredients in a rubber formulation is important for mechanical performance. after mixing, certain materials can remain undispersed within the rubber matrix, which could lead to critical flaws, influencing performance according to the griffith failure criteria. high resolution x-ray computed tomography (xct) offers a unique opportunity to measure phase

in the rubber compound. sulfur is available in varying degrees of fineness. amorphous sulfur (insoluble sulfur) is usually produced in industry through the rapid cooling of molten sulfur and can also contain rhombic sulfur (soluble sulfur), as insoluble sulfur tends to revert back to the rhombic state on storage.

- Why is insoluble sulfur a vulcanizing agent?
- Insoluble sulfur is important in the rubber industry as a vulcanizing agent since, when it is used, it can prevent rubber compounds from blooming during storage or during a production process without any adverse impact on the vulcanization process.
- Does soluble Sul-fur migrate across a rubber interface?
- The above migration profiles show that a significant amount of soluble sul-fur readily will migrate across a rubber interface. As expected, the magnitude of the change in sulfur concentration in-creases with increasing time and tem-perature and decreases with increasing distance from the plied up compounds interface.
- Does insoluble sulfur improve Bloom protection?
- Storage of insoluble sulfur for long periods at relatively high ambient temperatures also may lead to reversion, again lead-ing to a loss in bloom protection in the uncured compound. Thus, any improve-ment in the thermal stability of insolu-ble sulfur will provide enhanced bloom protection.
- Can A Com-mon curative migrate in a carbon black-filled natural rubber compound?
- The method was applied to a study of the migration of several com-mon curatives in a carbon black-filled natural rubber compound. The results were applied to a mathematical method described by Crank in order to test the validity of the procedure, to generate diffusion curves and calculate diffusion coefficients.
