Plastic melt (mass, volume) flow rate, melt density determination

The melt flow rate, formerly known as the melt index, is defined as: under specified conditions, the amount of thermoplastic material extruded within a certain period of time, that is, the mass of the melt passing through a standard die capillary every 10 minutes, expressed in MFR, in units g / 10min. The melt flow rate can characterize the viscous flow characteristics of thermoplastics in the molten state, and has important guiding significance for ensuring the quality of thermoplastics and their products and for adjusting the production process.
