XNR-400D Digital Display Plastic Melt Flow Index Tester

1.Application:

XNR-400D Digital Display Plastic Melt Flow Index Tester meet GB/T3682-2000, ASTM D1238-98, JB/T5456 and ISO1133 standards; used to determination of the melt mass flow rate (MFR) and the melt volume flow rate (MVR) of thermoplastics.

Using automatic sampling to determination of melt mass flow rate, balance weighing way.

To measure the melt volume flow rate is through the displacement sensor and automatic timing system, first to measure to time of the piston moves a specified distance, then calculate the volume flow rate according to the formula. The final result of two determination methods is displayed on the LCD screen and can output by the micro-printer.

This instrument measurement data accurate, operate simple, stable and reliable performance.

It is not only suitable for the higher melting temperature of polycarbonate (PC), fluorine plastic, nylon and other engineering plastics, but also suitable for polyethylene (PE), polypropylene (PP), polyoxymethylene (POM), polystyrene (PS) ABS resin, polycarbonate and other low melting temperature plastic.

This melt flow rate instrument is widely used in the production of plastic raw materials, plastic products, petrochemical and other industries, colleges and universities, scientific research 

departments and commodity inspection department.
