At the request of our German customer, we test our melt flow index tester temperature yesterday. and then we offer the good result to our customer. they are satisfy with it. and will order 3 sets for our melt flow rate tester later...
Melt flow rate (melt index)of thermoplastics is melt mass or volume which flow though the standard capillary die every 10 minutes, indicating by MFR.It’s different from thermoplastics viscosity in Molten state.
we test 190℃ point, after it reach the set temperature, and wait about 20 minutes to stable the temperature, then we get temperature like following:
set temperature: 190℃， Monitoring temperature：190.65℃ （within 0.8℃ floatingrange）
And we take test by MVR test method with standard PE materials
PE standard materials:
and we get test result like following:
