1. Characteristics and Usage 
XNR-400B Series Melt flow indexer is used to test melt flow index of all kinds of high polymer in viscosity flow. Under certain temperature and load, the melts quality and volume through standard neck ring mold is indicated with MFR . It is not only suitable for polycarbonate, polyarylester, Fluor plastic, nylon and other engineering plastics, but also suitable for polythene, polystyrene, polypropylene, ABS resin,  acetal resin and other lower fusion temperature plastics. It is widely applied to plastic production, plastic products, petrochemical industry and relative college, scientific research department and commodity inspection department.
 
2. Standards-compliant
2.1 ISO 1133 Plastics- Determination of the melt MFR and MVR of thermoplastics.
2.2 GB/T 3682-2000 Determination of the melt mass-flow rate (MFR) and the melt volume-flow rate (MVR) of thermoplastics
