What DSC values are required?

Enter melting enthalpy, cold crystallization enthalpy if present, the 100 percent crystalline reference enthalpy, and optional filler fraction.

Why subtract cold crystallization enthalpy?

Cold crystallization during heating contributes heat flow that should be subtracted from melting enthalpy for many polymer crystallinity estimates.

How is filler correction applied?

The calculation divides by the polymer fraction, which is 1 minus the entered filler mass fraction.

Review notes

DSC crystallinity depends on baseline choice, peak integration, and the selected reference enthalpy.

Methods note

Uses Xc = (DeltaHm - DeltaHcc) / (DeltaH100 * polymer fraction) * 100.
