Differential Scanning Calorimetry(DSC) Analysis and testing service

Differential Scanning Calorimetry (DSC)

DSC is a thermal analysis technique developed from Differential Thermal Analysis (DTA). It is defined as a method for measuring the heat flow of a sample relative to a reference material under temperature program control, abbreviated as DSC (Differential Scanning Calorimetry). DSC technology facilitates quantitative data acquisition for thermal effects while retaining DTA functions. It is widely used to: Determine melting heat, crystallinity, and isothermal crystallization kinetic parameters of polymers;

• Measure glass transition temperature (Tg);
• Study reactions such as polymerization, curing, crosslinking, and decomposition;
• Determine reaction temperature/zone, reaction heat, and kinetic parameters.
