melt flow indexer (MFI) for thermoplastics

Product catalog summary

Overview: The document provides detailed information about the Melt Indexer Series MI, which includes models MI-1, MI-2, MI-3, and MI-4. These devices are designed to measure the melt flow rate of polymers, adhering to ISO 1133 and ASTM D 1238 standards, and are certified under DIN EN ISO 9001:2000.

Specifications:

MI-1: Manually operated, suitable for single load tests. Features include a basic design with manual melt cutting and optional nitrogen purge.
MI-2: Offers automated single weight tests with advanced electronics, touch screen display, and options for nitrogen purge and electric weight handling.
MI-3: Automated with internal test weights, manual weight selection, and enhanced measurement accuracy.
MI-4: Fully automated with multi-load functionality, allowing for complex testing scenarios similar to rheometers.

Features:

All models include electrically heated test chambers with precise temperature control.
MI-3 and MI-4 models feature advanced displacement sensors and automated weight handling systems.
Options for die swell measurement, heated die plugs, and corrosion-resistant designs are available.

Performance:

MI-3 and MI-4 models demonstrate superior accuracy and temperature stability, as evidenced by round-robin tests.
The multi-load function in MI-4 provides improved accuracy by allowing relaxation phases between load changes.

Software Integration:

MFRHost software allows for data management and analysis, supporting multiple instruments simultaneously.
Data can be displayed numerically and graphically, with options for long-term statistical analysis.

Conclusion: The Melt Indexer Series MI offers a range of models to suit different testing needs, from basic manual operations to advanced automated systems with multi-load capabilities. The series emphasizes precision, ease of use, and integration with modern data management systems.

Many polymers are very sensitive when it comes to packing and pre-loading, where handling dierences directly impact measurement accuracy and repeatability. The MI-3 and MI-4 oer dierent ways to pack and how to apply a pre-load to the test material. This control covers the complete pre-heat/melt time. Either the time spent on each is controlled, or the position of the piston /material at a specic point in the barrel. The loads used are chosen manually with the MI-3 and automatically with the MI-4.
