thermal stability measurement


The thermal stability of polymers is usually determined by thermogravimetric analysis (TGA). During these tests, the decay reactions that take place in the samples – i.e., their decomposition by oxidation or thermal degradation – are reproduced … During these tests, the decay reactions that take place in the samples – i.e., their decomposition by oxidation or thermal degradation – are reproduced at elevated temperatures and thus drastically increased speeds. This variation over time is called drift. Laser Measuring Technologies Accu-Edge and Accu-Tool are cost-effective precision cutting tool measurement systems designed for your demanding environment. That’s why Metrohm offers you stability measuring instruments that allow you to perform automated accelerated aging tests for natural oils and fats, fat-containing foods and cosmetics, biodiesel, and chlorine-containing polymers such as PVC. You can use a control chart to monitor the stability of a measurement process by measuring a master or control part on the same system over time. Thermal stability of polymer is defined as the ability of the polymeric material to resist the action of heat [22] and to maintain its properties, such as strength, toughness, or elasticity at given temperature [23]. It represents the total variation in measurements of the same part measured over time. The PCB ® single and triaxial ICP ® accelerometers featured on this page are designed with a low temperature coefficient, wide operating temperature range, and good broadband measurement resolution, making them ideal for for any vibration measurement requiring tight control of amplitude sensitivity over a wide thermal gradient. ICP ® Accelerometers with Excellent Thermal Stability. Measurement of Heat Dissipation and Thermal-Stability of Power Modules on DBC Substrates with Various Ceramics by SiC Micro-Heater Chip System and Ag Sinter Joining Dongjin Kim , 1, 2 Yasuyuki Yamamoto , 3 Shijo Nagao , 2, * Naoki Wakasugi , 4 Chuantong Chen , … Predict stability with confidence. The formulation development group at Boehringer Ingelheim realized that having accurate, precise and high quality data for both thermal unfolding and aggregation is key to better predicting stability, developability and longer-term storage of their antibody candidates. The test method uses minimum quantities of material and is applicable over the temperature range from ambient to 800°C. The standard ASTM E2550 describes the thermal stability of a material as the “temperature at which the material starts to decompose or react and the extent of mass change using thermogravimetry “. Although the concept of thermal stability is easy to conceive, its determination is not trivial.
