Digital Display Plastic Melt Flow Index Tester(MFR Test Method)

Product Details


 Brief Introduction:  

The melt flow rate testing instrument (melt flow indexer) is a professional device for testing the melt flow rate of thermoplastics under certain condition. It can test PE, fluorine plastic, nylon engineering plastic, also suitable for polyethylene, polypropylene polystyrene, ABS resin, pom resins melting temperature lower plastic tests.

Melt flow rate (melt index)of thermoplastics is melt mass or volume which flow though the standard capillary die every 10 minutes, indicating by MFR.It’s different from

thermoplastics viscosity in Molten state.The melt flow index tester can be widely used in production and scientific research,factories, universities and research institutes structure and principle



Available standard

GB/T 3682-2000

ASTM D1238  Standard test method for Melt flow rates of thermoplastics by extrusion plastometer

ISO 1133   Plastics -- Determination of the melt mass-flow rate (MFR) and the melt volume-flow rate (MVR) of thermoplastics


1.This melt flow index tester is high precision temperature control, nitriding treatment for key parts. High strength and hardness, which insure the test result Accuracy.

2.: key components such as piston rod and cylinder are made of high-temperature, low thermal expansion coefficient materials, with a special surface heat treatment at high temperatures , less prone to distortion, and high hardness, not easy to wear, long-term use.

3.With an automatic cutting device driven by micro-motor, can set the cutting time, time control precision, small error.

4.Advanced ,Durable heating device, anti-high temperature, if there is damage also easy to replace

5.Equipped with micro-printer,can auto print test results, also can be saved the test result to USB
