Theoretical MFI Values of Common Polymeric Materials Reference

AI Thread Summary
The discussion centers on the search for theoretical values of Melt Flow Index (MFI) for common polymeric materials like polypropylene (PP), polyethylene (PE), polystyrene (PS), and polymethyl methacrylate (PMMA). It is noted that MFI is an empirical parameter, and there may not be theoretical calculations available for it. Participants suggest that comparing viscosities could be a potential approach, but caution is advised since viscosities are typically shear-dependent, whereas MFI testing does not provide information about shear dependence.

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.
