XNR-400B Melt Flow Rate Tester

Used to determine the flowability of thermoplastic polymers at high temperatures, such as polyethylene, polypropylene, polyoxymethylene, ABS resin, polycarbonate, nylon fluoroplastics, and other polymers.

Used to determine the flowability of thermoplastic polymers at high temperatures, such as polyethylene, polypropylene, polyoxymethylene, ABS resin, polycarbonate, nylon fluoroplastics, and other polymers.

The XNR-400B model adopts an industrial PLC programmable controller, a liquid crystal operation platform, and a separate temperature unit for the temperature section, with LED digital display. The automatic temperature control of this machine is divided into three cutting methods: manual, time control, and automatic. It can achieve two testing methods: mass method (MFR) and volume method (MVR); This machine can measure the melting density of raw materials at the test temperature, and the system also has temperature calibration function.
