Over the years, I’ve seen firsthand how evolving standards and increasing demands for precision are reshaping the way the ...
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 ...
Melt flow rate (MFR) testing reveals limitations in assessing LDPE samples, emphasizing the need for comprehensive viscosity ...
In the field of plastic processing, melt viscosity and melt strength are two crucial yet often confused core parameters. They serve as the "blood" and "bones" of the plastic processing process, ...
The new ASTM D1238 release supports automatic control of the pre-compacting, preheating and measurement phases for maximum accuracy and efficiency— ZwickRoell's Aflow is ready! KENNESAW, Ga., May 1, ...
Figure 1: A comparison of experimental and numerical results. Past theoretical work predicts that melt bands emerge perpendicular to the direction of the maximum rate of extensional strain. This ...
