Publication number: 20120232216Abstract: Using a target loading value and target intrinsic properties desired for a rubber formulation, two or more fillers are combined to create a blend having the desired intrinsic properties—i. e. a blend can be created emulating the desired intrinsic properties of a single filler system. In another exemplary aspect, knowing the individual loadings of fillers along with the target values desired for the loading of the blend and its intrinsic properties, individual intrinsic properties for at least one unknown filler that will be used to create the blend can be calculated. The unknown filler can then be identified by comparing the calculated intrinsic properties with the intrinsic properties of known fillers. The method allows e.g.) a manufacturer to blend a variety of suitable fillers while maintaining a more limited inventory of fillers than would otherwise be required for multiple rubber formulations.Type: ApplicationFiled: December 3, 2009Publication date: September 13, 2012Inventor: Xiaofeng Shaw Yang
