Can someone explain to me the major differences between a screw which is designed for LDPE and one which is designed for Propylene. Is it possible to have a screw which will extrude both resins half decent.
Thanks
My experience is that getting screwed has been problematic enough that I haven't actually had to worry about what was being extruded yet. Please keep us updated.

It depends on the application and the specific grades of each resin, percent crystalinity, MFI, expected ourput rates needed and drive HP among other things.
The short answer is yes, you can either do half decent though it may be more profitable to spend a few bucks up front and do each one very well.
