Both the rheological and the thermodynamical characteristic values of a binary system (e.g. solid and melting enthalpy of polymer blends) are generally deemed as being insufficiently describable over a linear average of the data from the raw components. This means for the simulation with SIGMA that before one starts a simulation, the material data of the binary systems should be determined. This would result in numerous measurements before the simulation process actually starts. If one only has the material data for the single components, the calculations for the binary systems using SIGMA will use the material data of the single components in the following ways:

• Rheologische Kenngrößen von Mehrstoffsystemen
• Thermodynamische Kenngrößen von Mehrstoffsystemen
• Dichten von Mehrstoffsystemen
