THE NEW MELT FLOW RATE TESTERS - NOT MERELY GRADERS ... BUT POWERFUL POLYMER ANALYZERS

摘要

The traditional melt flow rate (MFR) equipment has been broadly renovated in recent gears. In particular, important modifications have been applied to the reading system which have allowed full automation of the instrument. On the whole, these improvements may greatly enhance the quality control, which is still the aim of the basic instrument. As a consequence of the applied improvements, however, interesting new experimental fields have been opened, turning routine analysis equipment into interesting analytical tools. The paper aims to briefly show the new experimental possibilities; such as the evaluation of melt density, the filler content of a filled polymer, and the thermal stability.
