Description:
Thermal characterization of materials by using the DSC, TGA, and SDT are important techniques that are used by a wide variety of industries, including polymers, composites, pharmaceuticals, foods, petroleum, inorganic and organic chemicals, and many others. These instruments typically measure heat flow, specific heat capacity, weight loss, as a function of temperature and time. Properties characterized include melting, crystallization, glass transitions, cross-linking, oxidation, decomposition, and volatilization. These experiments allow the user to examine end-use performance, composition, processing, stability, and molecular structure, and mobility of the materials. Advanced thermal characterization techniques such as the Modulated DSC (MDSC), High-resolution TGA (Hi-Res), Modulated TGA, etc. are suitable for high sensitivity R&D as well as that are helpful to understand better the complex material behaviors, which is sometimes quite difficult to measure using the conventional techniques. The KnowHow Webinar will highlight those advanced characterization techniques along with their application examples related to polymeric materials such as plastics, composites, rubber, etc.

Description:
Thermoset polymers form the matrix in filled plastics and fiber-reinforced composites used in a diversity of products. These range from consumer items and auto body panels to advanced composites for printed circuit boards, aerospace structural components, and expensive, high-performance sports equipment. Rheological measurements have become the most important characterization technique because of their sensitivity to small changes in structure and the ease to monitor these structural changes. For the thermoset polymers, rheology (including dynamic mechanical analysis) provides details of structural changes, the gel point, and also processing parameters such as viscosity as a function of time. The advantage of the rheological technique is that it allows probing of the sample during the reaction with a small oscillatory deformation, which can generate viscoelastic material properties, such as the storage modulus, the loss modulus, and the tan delta all of which are characteristic of the changes of the material’s structure during cure. The KnowHow Webinar will demonstrate the various applications of the rheological characterization technique in the thermosetting polymer to predict its process behavior and how to evaluating its product performance.

Description:
Dynamic mechanical analysis is a sensitive method for exploring the structure, processability, and end-use performance of rubber and elastomeric materials. It enables characterization of the structural differences between materials and provides information about how the materials will process. Such information is important both for product development as well as process design and optimization. Most rubber materials are viscoelastic and full characterization of a material’s rheology requires elasticity information in addition to viscosity information. Dynamic mechanical analysis (DMA) is a uniquely powerful method because it measures both properties simultaneously. It measures the mechanical properties of a sample as it is deformed over a range of stress, strain, time, and temperature under different modes of the deformation such as tension, bending, compression, and shear. The KnowHow Webinar will exhibit how DMA characterization techniques are useful for evaluating the rubber and elastomeric materials to provide quantitative and qualitative information about the performance of the materials.
