Masterbatch product, namely hydrophobated silica and emulsion SBR, are TheĬritical difference is that the two major constituents of the silica To those found in a conventional emulsion rubber production plant. Masterbatch proceeds through a set of unit operations that are similar The overall scheme for the industrial production of the wet silica Industrial production of wet silica masterbatch Was conducted with a Brabender Plasticorder for small scale batches, and
Measured with a rotorless shear rheometer (RPA2000) using the ASTMĭ5289, D6204, D6602 and D7605 methods. Resistance was measured by the ASTM D5963 method. Scorch time were evaluated by the ASTM D1646 method. Tensile strength testing was conducted by the ASTM D412 method.Ĭure times were measured by the ASTM D2084 method. Rubber compound testing was carried out using standard ASTM test Helpful guidance is the goal of this article.Īll of the compounding ingredients used in this work are standardĬommercially available materials. TranslatingĬurrent compounds based on standard silica technology to one based onĮmulsil silica masterbatch requires some guidance and insight. The Emulsil silica masterbatch products are different.
Of the Emulsil silica masterbatch products, based on fullyįunctionalized and dispersed silica, clearly can simplify theĬompounding process for tire applications. Pass, and then on through the tire fabrication process. This complexity starts at the selection and use ofĪ silica filler, along with the type and amount of the silane couplingĪgent to use, and extends through the mixing process and the reaction Opening the door to the widespread use of silica as a reinforcingįiller also opened the door to greatly increased complexity in the tireĬompounding process. Or no sacrifice in other critical attributes of tire performance. Path to achieve a step change in reduced rolling resistance with little Theĭoor that opened with the widespread use of silica fillers provided a Precipitated silica in place of some portion of the carbon black. Time, with a key event marked by the emergence of the use of The type and use of reinforcing filler has evolved over Namely, the combination of reinforcing fillers, polymeric rubbers andĮxtender oils. Improvement of the materials used in the construction of the tire, In recent years there has been a shift in the focus towards the APA style: Emulsil silica masterbatch technology: compound design considerations for tire tread applications.Emulsil silica masterbatch technology: compound design considerations for tire tread applications."
