TCRT-3 Melt Flow Rate Tester
PIC-(TCRT-3 Melt Flow Rate Tester)
This melt flow rate meter is used to measure the melt flow rate of various polymers in a viscous state. It is suitable for engineering plastics such as polycarbonate, polyarylsulfone, and fluoroplastics with high melting temperatures, as well as materials with low melting temperatures such as polyethylene, polyethylene, polypropylene, ABS resin, and polyoxymethylene resin. It is widely used in plastic production, plastic products, petrochemical and other industries, as well as relevant universities, scientific research units, and commercial inspection departments.
This melt flow rate meter meets the testing methods for the mass flow rate and volume flow rate of thermoplastic melts specified in GB/T 3682.1-2018, ISO 1133:2011, and ASTM D 1238-2010 standards. Before use, please read this instruction manual carefully.
operational principle
Melt flow rate refers to the mass of thermoplastic material passing through a standard die every 10 minutes at a certain temperature and load, expressed as MFR, and the volume passing through a standard die every 10 minutes, expressed as MVR. Its value can represent the viscous flow characteristics of thermoplastic material in the molten state. Please refer to GB/T 3682-2000 Determination of Melt Mass Flow Rate and Melt Volume Flow Rate of Thermoplastics, Parts 6 and 7
