Recycled raw materials can also be chosen in case if the function of product made it possible to apply lower tight material.
Factory made regranulated materials or grinded recyclate materials of external origin often appears in the injection moulding workshops as well.
Merely the markings of MDA 643 and MDA 656 of recycled PP materials were known.
MFI measurement when extrusion materials are intended to use for injection moulding.
Three different PP raw materials were compared in our example.
