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.
