Melt Mass Flow Rate (MFR)

At Fleming Polymer Testing and Consultancy, we specialise in melt mass-flow rate (MFR) which can be used either as a one number indicator of polymer viscosity in the melt phase and/or a QA test. Melt mass flow rate features include:

• Indicative of weight average molecular weight
• Indicative of melt viscosity
• An easy to use 1 number quality test
• ability to measure melt density
• Essentially a simple capillary rheometer
• testing to ISO1133-1:2011
