Note 1—True heats of fusion are to be determined in conjunction with structure investigation, and frequently, specialized crystallization techniques are needed. Engage with an expert today. Differential Scanning Calorimetry, commonly known as DSC, is a thermo-analytical technique for polymeric and non-metallic materials.

Like all calorimeters, this technique tracks the amount of energy required to increase the temperature of a material by astj certain amount. Note 3—This standard is similar but not equivalent to ISO-2, The ISO procedures provide additional information not supplied by this test method. Formally confirming that your products and services meet all trusted external and internal standards.

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.

Send us a request Need help or have a question? Element offers a variety of methods for determining glass transition temperature and other important polymeric characteristics. This standard is not included in any packages. One of the pans is filled with sample and the other is kept empty as a control. Most commonly used for detecting glass transition temperature and other thermal properties, differential scanning calorimetry is one of the most efficient and cost-effective polymer test methods available.
A sample weight of 10 to 15 mg. Link to Active This link will always route to the current Active version of the standard. Melting or boiling points look like a adtm endothermic peak since they absorb energy, glass transitions look like a stair step, and most curing reactions show an upward exothermic peak.
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 asfm a molten state.
Combined with an FTIR analysis, a DSC thermal scan can be used to help further identify certain types of materials by their melting points and is a useful tool for checking plastic parts or resins for contamination not seen by FTIR.
This test method does not apply to all types of polymers as written see 6. DSC testing has been used for decades as a way to predict the behaviors of polymeric materials under different thermal conditions. Measures the temperature and energy of thermal transitions such as melting point, glass transition, and curing reactions.

The DSC head area contains equivalent sample and reference compartments located aztm to each other. When less energy is required to heat the sample as compared to the inert reference, an exothermic peak is observed.
Change in specific heat capacity, heat flow and temperature values are determined for these transitions. True heats of fusion are to be determined in conjunction with structure investigation, and frequently, specialized crystallization techniques are needed. This difference in energy is recorded as a peak on the DSC scan which indicates the temperature and energy of the transition.
