Elongation-Tester-D-MELT

D-MELT

The D-MELT enables the determination of melt index and elongation viscosity in one measurement. This combination is particularly interesting as a quick test in quality control (QC) for processing process of polymers.

The D-MELT makes it possible to also determine the Melt Elongation value (ME-value), a measure of the melt elasticity. Both measurements, ME and MVR, are done with just one filling of the test barrel. The ME-measurement is completed before the start of the standard-confirming MVR-measurement.

The ME-value is the force in the extruded strand at a certain draw-down ratio. This new combined method realizes the opportunity to determine a significant characteristic value of the extrusion behavior of your product in a quick, easy and cost-effective way. The D-MELT system and the ME-value are therefore ideal for continuous process monitoring or the inspection of incoming goods.
