Konstante Produktqualität von expandiertem Polystyrol (EPS) mittels STA

Jeder kennt EPS, das Verpackungsmaterial, das in der Unterhaltungselektronik für Fernsehgeräte oder Computer sowie für Isolierungen von Gebäuden. eingesetzt wird. Ausgangsbasis für EPS-Teile ist Polystyrol-Granulat, das homogen mit einem Treibmittel – meist Pentan − angereichert wird. Je mehr Treibmittel ein Mikrogranulat enthält, desto leichter lässt es sich im Prozessschritt Vorschäumen expandieren. Um die erforderlichen Verarbeitungsparameter genau bestimmen zu können, ist die Kenntnis des Treibmittelgehalts wichtig. Lesen Sie wie Thermogravimetrie Ihnen dabei hilft!

Investigating phase separation in elastomer-toughened adhesives with DMA

NETZSCH_DMA_elastomer toughened adhesive

Many of the polymers that are used in adhesives are relatively brittle materials. To improve their toughness, different fillers or toughening agents are incorporated in the adhesive formulations. Phase separation occurs during the process of monomer conversion to polymer. An understanding of the phase separation behavior under different curing conditions and the development of the morphology are important. This editorial summarizes the application of the DMA in the investigation of thermal properties and phase separation in elastomer-toughened ethyl cyanoacrylate adhesive bulk films.

Quality Control of Electronic Assemblies Using Thermomechanical Analysis

TMA Polymer Edition Electronic Assemblies1

A major source of failure of electronic assemblies is thermal expansion and the problems it causes. To make sure that the circuit base boards conform to a certain quality, IPC standards were put into place that require measurement of the thermal expansion, glass transition and softening point. Learn how you can comply to the standard with the new TMA 402 F3 Hyperion® Polymer Edition.

Measuring Viscoelastic Properties of Fiber-Reinforced Epoxy

When it comes to the characterization of fiber reinforced composites with dynamic measuring techniques many options are available, but they all have pros and cons for different materials and applications. In their paper, Huayamares et al. set out to answer some relevant questions by comparing measurements in 3-point bending and torsion mode. We summarize the main findings of the scientific paper and explain the measurements as well as the corresponding interpretation of the results depending on the use case.

LFA Measurements with Graphite Coating: Tips and Tricks

Thermal conductivity and diffusivity are the most important thermophysical material parameters for the description of the heat transport properties of a material or component. Since the Laser Flash Analysis is an optical method that needs to eliminate reflection, special attention needs to be put on the sample preparation, for instance with a graphite coating. Learn in the video below why the way of coating a highly conductive sample depends on which material property is to be determined.
