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

Do you need a plastic part or a film with very specific properties – such as temperature stability coupled with dimensional stability accurate to a hundredth of a millimeter and UV resistance – otherwise it cannot be used for its intended purpose? But how can you check whether all requirements have been met and, in addition, how can failures be analyzed?
Only if such questions are under control is it possible to permanently reduce the number of rejects. NETZSCH Analyzing & Testing offers a range of thermoanalytical methods for this purpose.
Many investigations in the field of polymers with lower stiffness require a measurement start below room temperature. As an alternative to existing solutions with Vortex tube and liquid nitrogen cooling, NETZSCH now offers the new compact AIC 80 intracooler for DMA measurements that works with chilled air. It reliably cools samples to -70°C without the use of liquid nitrogen.
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.
