Plastics: Flow rate ratio (frr) (NT POLY 171)

  • The Flow Rate Ratio (FRR) is based on two Melt Flow Rate (MFR) values instead of only one MFR as generally measured at present. MFR is a determination of the amount of melted material which, in ten minutes, is pressed through a die by a piston using a constant load.
