Melt flow index

    Where can i get the theoretical value of MFI for common polymeric materials such as PP, PE, PS, PMMA...as reference?

    I do not think there are theoretical calculations for such an empirical parameter. May be you could try to compare viscosities but keep in mind they are generally shear-dependent while the MFI test does not give you any info about shear dependence.
