Differential Scanning Calorimetry Analysis – DSC – ASTM D, ASTM D | Element

Please first verify your email before subscribing to alerts. When less energy is required to heat the sample as compared to the inert reference, an exothermic peak is observed. Weak glass transitions such as in polyethylene and polypropylene are usually not strong enough to detect. Add to Alert PDF. Assurance Testing Inspection Certification.

Element offers a variety of methods for determining glass transition temperature and other important polymeric characteristics. E Terminology Relating to Thermophysical Properties.

Melting or boiling points look like a downward endothermic peak since they absorb energy, glass transitions look like a stair step, and astn curing reactions show an upward exothermic peak.

Differential Scanning Calorimeter ASTM D, ASTM E, ISO

The pan filled with sample will require extra energy to heat through a transition such as a melting point because extra energy is required to change the molecule from a solid to a molten state.

To perform DSC testing, a small amount of material is heated at a predetermined rate. By making accurate measurements of heat capacity and temperature, differential scanning calorimetry can detect changes in material properties at exact temperatures, revealing important transition ranges and deterioration points.

Differential Scanning Calorimetry (DSC) Analysis

Phenolic materials typically give off water as a by product of curing which boils and shows a downward endothermic peak in the same range as the curing exothermic peak so they cancel each other out.
