Presentation

Application of new additive silica dispersant

Green tires are gradually being accepted by the public for their comfort, safety, environmental protection and energy saving, and demand and production are increasing day by day. A large number of research results show that using silica as a reinforcing filler in tire tread rubber can significantly reduce the rolling resistance of the tire. However, as the amount of silica in the formula increases, the rubber compound mixing process becomes difficult, as well as the silica black dispersion difference. Riba New Material Technology is committed to developing new silica dispersants to help tire companies solve the problems faced by high-fill silica formulas in rubber compound mixing. This presentation introduces the mechanism of action of the new silica dispersant, its impact on the process and physical properties of the rubber compound, and relevant experimental research data.
