QualiFi-2000 Series - MFI Melt Flow Indexer | MFI Tester:

Melt Flow Index Tester QualiFi-2000 Series, available in 2 variations, are entry-level, low-cost bench top instruments that measure the melt mass-flow rate (MFR) and melt volume-flow rate (MVR) of a wide range of thermoplastic raw materials (granulate).

This entry level QualiFi-2000 Series Melt Flow Indexer conforms to all International Melt Flow Resistance standards, including ISO1133, ASTM D1238. Any temperature within 100°C - 450°C (212 F -842 F) can be accurately controlled.

Using advanced electronic measurement technology, LCD display, and micro-printer (Model AB), the system obtains the melt mass flow rate (MFR) or melt volume flow rate (MVR) (Note: single measurement value and the average value of multiple cuts). The control system can measure and display the temperature value in real-time. It has features such as upper limit temperature protection, constant temperature sound prompt, and response time prompt.

Using advanced PID control technology and a high-speed, high-resolution sampling circuit, the machine features a fast heating rate, high constant temperature precision, and quick restoration of the constant temperature state after filling.

The ASTM D1238 and ISO 1133 standard test methods cover the determination of the rate of extrusion of molten thermoplastic resins using a Melt Flow Indexer also known as extrusion plastometer. After a specified preheating time, resin is extruded through a die with a specified length and orifice diameter under prescribed conditions of temperature, load, and piston position in the barrel.

Method A is used to determine the melt flow rate (MFR) of a thermoplastic material. The units of measure are grams of material/10 minutes (g/10 min). It is based on the measurement of the mass of material that extrudes from the die over a given period of time. It is generally used for materials having melt flow rates that fall between 0.15 and 50 g/10 min.

Method B is an automatically timed measurement used to determine the melt flow rate (MFR) as well as the melt volume rate (MVR) of thermoplastic materials. MFR measurements made with Procedure B are reported in g/10 minutes. MVR measurements are reported in cubic centimetres/ten minutes (cm3/10 min).

Procedure B measurements are based on the determination of the volume of material extruded from the die over a given period of time. The volume is converted to a mass measurement by multiplying the result by the melt density value for the material. Procedure B is generally used with materials having melt flow rates from 0.50 to 1500 g/10 min.

Our MFI Tester, QualiFi-2000A, meets ASTM D1238 Method A for MFR (Melt Flow Rate) testing of thermoplastics.

The MFI Melt Flow Indexer QualiFi-2000AB meets both ASTM D1238 Method A and B for MFR (Melt Flow Rate) and MVR (Melt Volume Rate) testing of thermoplastics.
