In Powder bed fusion there is no flow and no shear rate. For powder coalescence, the local molecular motions and entanglements across the layers are important. So today, Dr. Natalie Rudolph will be focusing on the rotational rheometry.
Rheology studies the deformation and flow of fluids. Traditionally, capillary rheometers have been used to measure the shear viscosity and elasticity of viscous materials at high shear rates. Learn why you need a capillary rheometer and what data you can obtain.

Identify is the most comprehensive database system in Thermal Analysis! In a nutshell, Identify can be used for the recognition and comparison of measurement curves. Signals of types DSC, TGA, DIL/TMA and cp are supported, curves can be found and overlaid easily. This article highlights the great database contents of Identify (status 11/2019): The Identify database already contains about 2300 database entries!
Carbon black is a virtually indispensable product for the polymer industry, whether in rubber mixtures as a strengthener, pigment for plastics, conductive agent or UV stabilizer, depending on the occurrence, particle size and structure. Therefore, it is crucial to evaluate and confirm its level and precise dispersion in order to avoid adverse effects on the final material costs and mechanical properties
Professor Dr Tim. A. Osswald and Dr Tobias Pflock talk about the effect temperature has on the polymer’s properties. The room temperature modulus is often the only value given to describe the mechanical property of a polymer material. But temperature dependence of mechanical performance of polymer material significantly differs to that of other materials such as metals or ceramics and is vital information for many everyday applications of polymers.
