This festive season of the year is for many the season for baking cookies and biscuits. But then, we have to decide: parchment paper or silicone baking mat? Today, we are answering the question if the two options are safe to use.
Fillers are added to a polymer matrix to improve the mechanical performance of the finished product. The orientation of such fillers depends on the processing conditions. Learn how the overall content, shape and orientation of copper fibers influence the coefficient of thermal volume expansion.
In general, the addition of fillers leads to an increase in mechanical performance. While a critical length of the fillers is needed to have an effect on the strength of components, the stiffness is already increased with fillers with small aspect ratios. To understand how the stiffness or modulus change as a function of the filler geometry and filler content, Dynamic Mechanical Analysis (DMA) can be used. Learn more in our article!
Thermoplastic polymer melts are widely used in many modern industrial processes to manufacture a multitude of objects. Learn which properties measured with a Kinexus rotational rheometer help solve real-life polymer processing problems.

Der Einsatz von endlosfaserverstärkten Kunststoffen mit thermoplastischen Matrixsystemen in der Luftfahrtbranche erfordert die Entwicklung geeigneter Fertigungstechnologien für diese Materialkombination. Ein potentialträchtiges Verfahren ist in diesem Kontext Automated Fiber Placement (AFP). Lernen Sie mehr über die Prozessketten zur Herstellung von Strukturbauteilen und warum der Kristallinitätsgrad entscheidend ist.
The use of continuous fiber-reinforced plastics with thermoplastic matrix systems in the aviation industry requires the development of suitable manufacturing technologies for this material combination. One promising process in this context is Automated Fiber Placement (AFP). Learn more about the process chains for the production of structural components and why the degree of crystallinity is decisive.
One of the principle reasons that polymers are used so widely is because they are relatively cheap to form into complex shapes in the molten state which is a huge change in rheology from a solid starting material through to a solid end product. Learn how to determine flow curves, carry out creep tests and measure viscous and elastic properties.
It is imperative to understand how thermoplastics flow when being processed. Learn about the time dependence of flow properties and other important characteristics.
