Q: How to optimize MFR data?

If you use an extrusion plastometer (melt indexer) to testthe melt-flow rate (MFR) of resins, you can make your life a whole lot easier by paying close attention to the procedural steps detailed in the test standards, to ensure accuracy, efficiencyand smooth operation. This is true whether you are conducting occasional tests or running extensive automated testing in a lab setting. Many say they meet a published test standard, but in realitythey are not following the test standard exactly as written.

Testing in plastics can be done on the plant floor to improve quality in molded or extruded parts, and off-line in the lab not only to check if parts are up to specification but also to evaluate the quality of incoming raw materials.

FAQ: Testing

How to optimize color evaluation of recycled plastics?

Whether for resins with PCR content or for virgin resins, the keys to minimizing variability in your color evaluation are to use the right color-measurement instrument (spectrophotometer—benchtop or hand-held) and to create good working methods, that is, establishing a standard operating procedure (SOP).
