Differential Scanning Calorimeter DSC for Polymer Thermal Analysis

Differential Scanning Calorimeter

Accurate Thermal Transition and Heat Flow Analysis for Material Research and Quality Control

The CHEESION Differential Scanning Calorimeter, also known as a DSC analyzer, is designed to measure the difference in heat flow between a sample and a reference under a controlled temperature program.

The instrument helps laboratories and manufacturers determine important thermal properties, including glass transition temperature, melting temperature, crystallization temperature, enthalpy change, specific heat capacity and oxidation induction time.

CHEESION DSC instruments are suitable for the thermal characterization of polymers, plastics, rubber, resins, films, cable materials, composites, pharmaceuticals, chemicals and other advanced materials.

By providing accurate and repeatable thermal data, the DSC analyzer supports material identification, formulation development, incoming material verification, production quality control and finished-product evaluation.

The CHEESION Differential Scanning Calorimeter is widely used in plastics, polymers, rubber, cables, films, pipes, automotive components, batteries, pharmaceuticals, chemicals, and advanced materials.

It can measure glass transition, melting, crystallization, enthalpy, crystallinity, and oxidation induction time. These results help users evaluate material consistency, optimize formulations, verify raw materials, improve processing conditions, and assess thermal stability and aging resistance.

DSC is suitable for R&D laboratories, universities, research institutes, manufacturers, and quality control departments. It supports applications such as polymer characterization, cable and pipe material testing, automotive component analysis, battery safety studies, pharmaceutical research, supplier verification, and finished-product inspection.

Measurement Capabilities

Glass Transition Temperature

DSC detects changes in heat capacity associated with the glass transition of amorphous and semi-crystalline materials. This measurement is commonly used to evaluate polymer flexibility, service temperature and formulation consistency.

Melting and Crystallization

The instrument measures melting and crystallization temperatures as well as associated enthalpy changes. The results can be used to assess material purity, crystal structure, thermal history and processing conditions.

Degree of Crystallinity

By comparing measured melting enthalpy with reference values, DSC can help estimate the crystallinity of polymers and evaluate the effects of cooling rate, processing and additives.

Oxidation Induction Time

Oxidation induction time testing evaluates the oxidative stability of polymer materials under controlled temperature and oxygen conditions. It is commonly applied to polyethylene pipes, geomembranes, cable insulation, films and other products requiring long-term aging resistance.

Specific Heat Capacity

With an appropriate test method and calibration, DSC can be used to determine the specific heat capacity of materials over a selected temperature range.
