MELT INDEX The evolution of the melt index measurement!

Melt Index mi2 Series Flexible, compatible, systematic: Step by step from the simple boarding device mi2.1 to the upgraded semi-automated unit mi2.3. The evolution of the melt index measurement! • Brilliant touch screen display for the operation, program control and display of the test results • Temperature control by 2 heater elements, resolution 0.01°C • 5 calibration sets for set temperature with respective parameter files • Storage of up to 500 parameter sets with 3000 measurements for each parameter set in stand alone operation • High-resolution position transducer to measure volume...

Melt Index MI-3 • The selected test weights are internally installed; manual and therefore dangerous weight handling is eliminated • Users may simply select test weights using a lever that activates the electrical weight handling system • A specially designed guidance system for the test weights ensures that measurements are not influenced by weights being slightly slanted, skew, or off center, which would lead to errors • To ensure convenient access to the test chamber, it can be swiveled by 45°. The use of a special cable system ensures many years of service and is especially designed to...

Options mi2 series, MI-3, MI-4 • Die swell unit • Manual die plug (also heatable for polymers with high temperature) • Automated die plug • Manual or automated melt cutting unit (also for sticky polymers) • Interfaced melt density determination by integrated balance • Time saving: Pneumatic compress and press through device for high viscous materials (MI-3 and MI-4) • Nitrogen purging for hygroscopic polymers • Barrel and piston in corrosion resistant or abrasion resistant design • Automated backup of all values in the event of power failure via UPS Multi-Load-Test Glancing at the MI-4, one...

Loading functionality Compressing Many polymers are very sensitive when it comes to packing and pre-loading, where handling differences directly impact measurement accuracy and repeatability. The test devices offer different 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 specific point in the barrel. The loads used are chosen manually with the mi2.3 and MI-3, automatically with the MI-4. Melting time Post measurement First compression...

Load 1 Load 2 Load 3 Load 4 Load 1 Load 2 Load 3 Load 4 Relaxation area Conventional multiple load tests do not provide any relaxation phase while load changing: this results in higher dispersed test values compared to single test load measurements (figure at left). With our new multiple load function (up to 8 weights), being integrated in the MI-4, the material is given enough relaxation time between load changes to minimize any pre-shearing influences. The result is that both, single load tests and multiple load tests are now in high conformity (figure at right). Vergleich 190°C Fühler...
