Paints, coatings and inks, polymers, food, pharmaceuticals and cosmetics, bitumen and petrochemical – the list goes on! These and many other materials have unique properties that are researched and quality-controlled using rheological test methods. Our new free-of-charge booklet is helpful to understand how the flow properties of materials can be related to their rheological analysis!
NETZSCH Instruments North America is hosting the combined 35th International Thermal Conductivity Conference and 23rd International Thermal Expansion Symposium in Boston Massachusetts, USA. Due to the Covid pandemic, the ITCC board has decided to postpone the event until 2022!
Governments set strict building insulation regulations in place to reduce carbon emissions. Consequently, a lot of effort goes into the engineering of materials with very low thermal conductivity to supply the market with even better thermal insulation materials. Learn how the NETZSCH HFM 446 Lambda Eco-Line allows accurate and fast determination of thermal conductivity and thermal resistance!
Before we dive into the material science of processing materials with different Additive Manufacturing technologies, we introduce common material groups, distinct molecular structures of material classes as well as discuss other materials used for non-technical applications.
Chocolate is one of the world’s favorite snack foods. The texture, or mouthfeel, of chocolate is critical for the consumer perception of product quality. It is possible to finely control the textural aspects of the signature flavor of chocolates. The mouthfeel can be characterized through the determination of flow ‒ by rheology. Learn how to do this in our article!
Additive Manufacturing (AM) or 3D printing has matured over the last decades and has become a constant in our product design and development cycles and is debuting in more and more new products. At NETZSCH Analyzing & Testing, we see more and more customers in the field of Additive Manufacturing using our equipment to select materials and optimize their processes. Learn more about Additive Manufacturing in our articles and videos!
During the Vat Photopolymerization process, the component is built-up in layers in a liquid resin vat using a UV laser beam to selectively cure the resin. Learn how the degree of thermal cross-linking of a two-component resin is determined by the preceding cross-linking reaction during photo-polymerization.
Popular materials for lightweight applications are glass and carbon fiber-reinforced plastics. The properties of the composite material are determined by the manufacturing process conditions. Therefore, it is crucial to know the curing state reached during manufacturing as well as the correlation between the glass transition temperature and degree of cure.
In 2020, we started our “Material Science in Additive Manufacturing” video series as we faced an increasing interest from the industry to perfect their 3D printing processes and outcomes. First, we focused on understanding the 7 different Additive Manufacturing (AM) technologies. In the advanced section, we will dive deeper and look at the underlying material science as well as the methods suitable to analyze the materials and to optimize processes
Significant efforts have been made to model and simulate the Selective Laser Sintering process as information about the temperature field in lower layers is difficult to measure. Learn how specific heat capacity can help!
