Xpander: a Revolution for Dynamic Mechanical Analysis

Metravib has launched Xpander which, used in association with a Metravib DMA instrument, enables DMA test campaigns on a large number of specimens to be entirely automated.

Metravib explains that Dynamic Mechanical Analysis serves to characterise the viscoelastic properties of materials (rubber and polymers) to an extremely high level of accuracy. In particular, it is the most accurate technique available to determine the glass transition of these materials (TG). Such properties are central to the performance and functional properties of manufactured products. It is essential to measure such properties in order to comply with new regulations.

According to Metravib, the diversity of formulations used and varied sourcing of raw materials means that laboratories must conduct increasing numbers of tests. As a pioneer in the automation of dynamic testing, Metravib says it has been supplying the leaders of the rubber and tire industries with robotic dynamic mechanical analysers for more than 15 years.

Now, Metravib claims that it is confirming its position as a leader in this field. Xpander has been designed to significantly increase the number of tests performed by DMA instruments in various test modes: compression, tension and shear. Tests are performed around the clock and no longer require the presence of an operator.

It says that Xpander's flexibility makes possible to accommodate with material specimens of various shapes and sizes. The specimen handling automation targeted since the original design of DMA+ series ensures keeping high performance in their robotic mode.

In addition to a high test throughput, Xpander is also said to offer several other advantages:

  • Reduced labour costs.

  • Improved accuracy and uniformity of results.

  • Elimination of human error.

  • Improved operator safety.

Furthermore, as Hugues Baurier, Metravib DMA International Trade Manager, tells us, “Xpander and the new DMA+ range have been designed taking account of industrial expectations in terms of accuracy, performance, productivity and ergonomics, as expressed by worldwide leaders in the rubber and polymers sector.”

With Xpander, METRAVIB offers automated Dynamic Mechanical Analysis instruments with configurations suitable for R&D, industrial testing and quality control departments.
