Melt Flow Rate in Extrudable Thermoplastics

Who knows the melt flow rate in extrudable thermoplastics?

The melt flow rate (MFR) in the properties of extrudable thermoplastics is a physical quantity that characterizes the molecular weight of the plastics. The test method is that the melt flow rate of the tested plastics is determined by adding melt flow rate meter and changing the plastics into melt state under a certain temperature and load (commonly used 216 Og). The melt flow rate of the tested plastics is defined as the number of melts (g) flowing out from the standard capillary within 10 minutes.
