Ⅰ.XNR-400B Melt Flow Rate Instrument is used for determination of flow properties of thermoplastic
high polymer under high temperature according to test methods of GB/T3682, ISO1133 and ASTMD1238. It
 is used to determine the melt flow rate of high polymer such as PE, PP, POM, ABS, PC, nylon and Fluor
 plastics, etc. It is widely supplied to the production and research of factory and science and research
institute.
