Product Name: High Efficiency Melt Flow Indexer Plastic Melt Flow Indexer Model NO.: MFI Trademark: JINJIAN Transport Package: Wooden Specification: ISO1133 ASTM1238 Origin: China HS Code: 90248000 Product Description The Melt Flow Indexer is related to the melted material viscosity.It allows the operator to make an estimation of"mean molecular weight",at the same time gives an indication of "melt flow ability"through a die. The melt index is defined as the weight or the volume of melted material flowing through a calibrated die,under the effect of a pre-determined force,at constant temperature and for the total time of 10 minutes.
