LR-A001-A Melt Flow Index Tester
Discription:
Melt flow rate testing instrument can be used for ABS, polystyrene, polyethylene, polypropylene, polyamide, fiber resin, acrylate, POM, fluorine plastic, polycarbonate and other plastic materials, the melt flow rate (MFR) or the melt volume flow rate (MVR) to be determined.
Standard:
GB/T3682-2018,ISO1133-2011, ASTM D1238
LR-A001-A Melt Flow Index Tester
Product Character:
1.English LCD Touched Screen.?
2.Hａnd automatic cutting material.
