DIFFERENTIAL SCANNING CALORIMETRY（DSC）
Simple & Powerful
Differential scanning calorimetry is a technique that measures the relationship between the difference in heat flow to a substance and a reference substance and temperature or time under programmed temperature control. DSC has become one of the most common analytical instruments for studying polymers, pharmaceutical synthesis, food, plastics, rubber, coatings, etc.
Setline DSC is completely equivalent to the original factory level in terms of production process, raw material control, software matching, and final performance indicators. Under the condition of greatly reduced costs, it has truly achieved the complete elimination the difference between Chinese manufacturing and European and American products from the process level, technical means and performance. As a new generation of general-purpose DSC/STA, Setline® series has created a new era of localization of high-quality thermal analyzers!

The DSC curve records the heat flow of 25 mg PET (polyethylene terephthalate) sample heated at 10°C/min. From left to right in order: glass transition, exothermic crystallization of amorphous phase and endothermic melting. These are the important datas to understand the thermal properties of this polymer.
Oxidation induction time (OIT) of synthetic rubber at 210 °C.
The sample was heated to 210 °C under an inert atmosphere (nitrogen). After the signal stabilizes (20 minutes), the atmosphere is converted to oxygen. An exothermic effect of polymer oxidation was observed at about 45 minutes. The oxidation induction time is 34.6 minutes. OIT can be increased by adding antioxidants.
The glue sample is cured before testing to eliminate its thermal history; the fully cured sample is tested for Tg.
