Applications
Melt Flow Index Tester is used to determine melt-mass flow rate (MFR). It is applicable not only to the higher melting temperature, such as masterbatches, polycarbonate, nylon, fluoro plastics, poly oxide and other engineering plastics, and it also applies to plastic measurement of melt lower temperature, such as polyethylene, polystyrene, polypropylene, ABS resin, poly formaldehyde resin. At the same time, it is widely used in plastics raw materials products, the petrochemical industry and related universities, scientific research institutes, and commodity inspection departments. It is based on designed and manufactured according to latest national and international standards.

Digital displays and programmable timers simplify operation, making testing streamlined and repeatable.
Durable Construction for LongevityBuilt with a stainless steel barrel and a hardened, ground steel plunger, the MFI Tester is crafted for long-lasting performance. The rigid steel frame lends structural strength, while the inbuilt digital gauge enables precise measurement. The included sample cutter and standard 2.095 mm die orifice meet international compliance requirements for melt flow testing.
Versatile Laboratory ApplicationsIdeal for dealers, distributors, manufacturers, and researchers, the MFI Tester is suitable for a variety of polymer testing scenarios. Its semi-automatic operation and fixed stroke design, as per ASTM standards, make it perfect for analyzing the melt flow of thermoplastics in research, quality control, and production environments.
FAQs of MFI Tester:
Q: How does the MFI Tester measure the melt flow index of thermoplastics?
A: The MFI Tester determines the melt flow index by measuring the amount of polymer extruded through a standard die orifice (2.095 mm) under specific temperature and load conditions, following ASTM D1238 or ISO 1133 methods. The digital LED display and inbuilt digital gauge provide precise, real-time measurement readings.
Q: What is the process for setting up and using the MFI Tester?
A: To use the MFI Tester, simply power it using a 220-240 V AC supply, set the required temperature on the soft touch keypad, and wait for the unit to reach the desired temperature (about 6-8 minutes). Insert your sample in the barrel, operate the plunger, and collect extrudate using the included sample cutter. The programmable timer assists in maintaining uniform test conditions.
Q: When should the testers cooling system be used?
A: The MFI Tester offers both a natural cooling system and an optional fan-assisted cooling. For standard lab use, natural cooling is often sufficient. However, fan-assisted cooling may be helpful for rapid temperature reduction between tests or to enhance safety during extended operation at high temperatures.
Q: Where is the optimal environment to operate the MFI Tester?
A: The MFI Tester is intended for indoor laboratory use, ideally in controlled environments to maintain accuracy and safety. It operates best at ambient room temperature, free from excessive humidity or dust that might interfere with electronic components or melt flow measurements.
Q: What materials is the device compatible with, and what benefit does it offer for plastics manufacturing?
A: This tester is compatible with a wide range of thermoplastics. By providing accurate melt flow index values, it enables manufacturers to assess material quality, batch consistency, and suitability for various processing techniques, thereby ensuring higher product quality and process efficiency.
Q: How does the digital programmable timer function benefit operations?
A: The digital programmable timer allows you to precisely control test duration, improving repeatability and reducing human error. This ensures that each MFI test is performed under consistent conditions, critical for reliable comparative analysis.
Q: What advantages does the microprocessor-based PID temperature controller offer?
A: The microprocessor-based PID controller delivers highly stable temperature regulation (accuracy: 0.1C), minimizing thermal fluctuations during testing. This leads to more reliable test outcomes and safeguards against overheating, protecting both the polymer samples and the tester itself.
