This test method covers the determination of heat of fusion and heat of crystallization of polymers by differential scanning calorimetry. Subscription pricing is determined by: Sensors with high calorimetric sensitivity, short time constants and a condensation-free sample chamber in the calorimeter cell guarantee high detection sensitivity and stable, reproducible baselines over the entire life cycle of astk calorimeter: Eutectic purity Specific heat c p Compatibility between components Influence of aging Distribution of the molecular weight peak form for polymers Impact of additives, softeners or admixtures of re-granulates for polymer materials What is the Difference Between DSC and DTA?
It unites excellent performance and highest flexibility. Designed especially for the characterization of polymer materials, its integral approach consists not only of the DSC instrument alone, but also incorporates the entire analytical process chain from sample preparation to evaluation. The sample is heated at a controlled rate and a plot of heat flow versus temperature is produced. Numerous upgrade possibilities allow adaption of this cost-effective calorimeter system to sophisticated applications.

Combined with an FTIR analysisa 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 standard is also available to be included in Standards Subscriptions. Characteristic temperatures melting, crystallization, polymorphous transitions, reactions, glass transition Melting, crystallization, transformation and reaction heats enthalpies Crystallinity of semi-crystalline substances Decomposition, thermal stability Oxidative stability OIT, OOT — oxidative-induction time and oxidation onset temperature, respectively Degree of curing in resins, adhesives, etc.
The sample compartment is where an encapsulated sample of about 10 to 15 milligrams is placed for testing.
