The two main MFI test standards are ASTM D1238 - “Standard Test Method for Melt Flow Rates of Thermoplastics by Extrusion Plastometer” and ISO1133 – “Determination of the Melt Mass-Flow Rate (MFR) and ...

Among the first instruments plastics molders, extruders, and compounders are likely to consider when outfitting a new lab is a melt-flow indexer or “melt indexer.” Known as an extrusion plastometer in ...

To understand the effect of processing and co-monomer content on interfacial adhesion, we quantified adhesion levels of bilayers of a polyethylene (PE) with various polypropylenes (PPs) prepared using ...
