Melt flow rate is also called melt index, which is defined as: under the specified conditions (specific temperature and pressure conditions), the amount of thermoplastic material extruded within a certain period of time, i.e., the melt passes through the mass of the standard orifice capillary tube every 10 min, expressed by MFR, the unit is g/10 min. Melt flow rate characterizes the viscous flow characteristics of thermoplastic in the molten state, which is important for ensuring the quality of thermoplastic and its products, and for adjusting the production process, all of which are important guiding significance. The melt flow rate can characterize the viscous flow characteristics of thermoplastics in the molten state, which is important for ensuring the quality of thermoplastics and their products and adjusting the production process.
pump melt gear pump for plastic extruder
Zhengzhou BATTE as a professional melt gear pump manufacturers, for how to effectively select the right type of extrusion melt pump for the user, the material melt flow rate is very important. When the melt index of the material is less than 1g/10min, the viscosity of the material is very large, poor mobility, polymer melt pump speed is relatively small, corresponding to the choice of models to be larger; the melt index of the material is greater than 10g/10min, that is more dilute, mobility is better, melt pump speed is larger than the corresponding models to be smaller.
