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

The traditional melt flow rate (MFR) equipment has been broadly renova ted in recent gears. In particular, important modifications have been applied to the reading system which have allowed full automation of th e 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 exp erimental 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.
