The compounded rubber has a high viscosity
Thread Content
Today, engineers from the tire factory told us that the Mooney viscosity of the compounded rubber is high. I would like to ask everyone: what properties of carbon black are related to a high Mooney viscosity? This post was last edited by QXZ-1966 on 2009-4-15 at 16:10.]
You must be their supplier of carbon black. The Mooney viscosity of the compounded rubber is influenced by many factors, including the mixing process, the initial Mooney viscosity of the raw rubber, plasticizers, fillers, etc. It has little relation to the structure of carbon black; the impact of carbon black structure on Mooney viscosity is mainly related to particle size. In the inspection standards for tire raw materials, there is no Mennix test for carbon black, nor are any specific indicators specified. If they claim that the quality of your carbon black is problematic on this basis, you can confidently tell them that such an assertion is inaccurate.
