RT-701B Plastic Melt Flow Rate Index Tester
RT-701B Melt Flow Rate Tester for Plastic is used to determine the melt flow rate of thermoplastics (MFR+MVR; units: g/10min) instrument.
For polyethylene, polypropylene, polyoxy methylene, ABS resin, polycarbonate, nylon, plastics and other polymers fluoride melt flow rate at high temperature determination.
Product Details：
Meet Standards:
The RT-701B melt flow rate meter is suitable for determining the specified thermoplastic melt mass flow rate in the national standard “Determination of GB/T3682-2000 Thermoplastic Melt Mass Flow Rate and Melt Volume Flow Rate.” This standard is equivalent to using the provisions of ISO 1133:1997, which can also meet the ASTM D1238 test standard.

2 . Standard test load (kg ,8 grades)
1st grade :0.325kg = (piston stem +weight tray +heat insulation sheath +weight # 1) = 3.187N
2nd grade :1.200kg = (0.325+weight # 2 0.875) = 11.77N
3rd grade :2.160kg = (0.325+weight # 3 1.835) = 21.18N
4th grade :3.800kg = ((0.325+weight #4 3.475) =37.26N
5th grade :5.000kg = (0.325+weight #5 4.675) = 49.03N
6th grade :10.000kg = (0.325+weight #5 4.675+weight #6 5.000) =98.07N
7th grade :12.500kg = (0.325+ weight #5 4.675+weight #6 5.000+ weight #7 2.500) =122.58N
8th grade :21.600kg = (0.325+ weight #2 0.875+ weight #3 1.835+ weight #4 3.475+ weight #5 4.675+weight #6 5.000+ weight #7 2.500+weight #8 2.915) =211.82N
The test load relative error shall not be more than ±0.5% .
