Differential Scanning Calorimeter DSC is designed to determine the inner heat transition relating to temperature and heat flow, it is widely used in the field of polymer development, performance testing & quality control. DSC research and development includes the following field: glass transition temperature, melting point, cold crystallization, crystallization, phase transition, Enthalpy, oxidation induction time (OIT).
Application
It is used to determine the time of automatic catalytic oxidation of the sample at room temperature hydrogen, and to evaluate the thermal stability of the sample. It is suitable for plastics and rubber materials.
