Differential Scanning Calorimetry (DSC) is a powerful technique to determine the heat flowing in-and-out of a material during a defined temperature & time profile. This heat and the temperatures & conditions at which it is manifested can provide information on:
- material properties: heat capacity,...
- physical transitions: phase transitions (e.g. melting, crystallization), glass transitions, polymorphic transitions,...
- chemical reactions & kinetics: polymerization, crosslinking, curing, oxidation,...

More specifically the following parameters can be determined:
- melting temperature & enthalpy: please see our offering "Differential Scanning Calorimetry (DSC): determination of melting point & enthalpy"
- crystallization temperature & enthalpy of crystallization, degree of crystallization
- glass transition temperature (& step height)
- specific heat capacity
- Oxidation Induction Time: please see our offering "Differential Scanning Calorimetry (DSC): determination of Oxidation Induction Time (OIT)"

Please contact us to further discuss your specific measurement requirements.

The Oxidation Induction Time is the time for which an antioxidant stabilizer system present in a material inhibits oxidation while the material is held isothermally at a specified temperature in a stream of oxygen.
Practically a sample is placed in a Differential Scanning Calorimeter (DSC) and heated to a specified temperature under N2 after which the atmosphere is changed to O2 and the temperature is kept constant (i.e. isothermal). A strong increase in exothermic heat flow indicates the time of depletion of antioxidant stabilizers and the onset of oxidation reactions.
Make sure to include information on the aim of your measurement, your desired measurement conditions (temperature, atmosphere,...) and the chemical nature (e.g. PP, PE, PET, PA,... preferably with a safety datasheet) of your polymer with your order. Extra costs may apply depending on the complexity and duration of your requested conditions.
For more information or more complex requirements, please contact us.

Differential Scanning Calorimetry (DSC) allows the determination of the polymer's melting point and the enthalpy of melting: when melting starts, the added heat is used for the phase transition (i.e. endothermic process), not for an increase in temperature. The peak of the heat flow indicates the melting temperature while the surface area of the peak is a measure for the enthalpy of melting.
Make sure to include information on the aim of your measurement, your desired measurement conditions (temperature range, heating rate,...) and the chemical nature (e.g. PP, PE, PET, PA,... preferably with a safety datasheet) of your polymer with your order. Extra costs may apply depending on the complexity and duration of your requested conditions.
