TGA and DSC behaviour as function of the temperature.

Phase	Range (°C)	TGA behaviour	DSC behaviour	Color
I	26–100 °C	slow rate of mass loss	no event	white
II	100–135 °C	mass loss at increased rate	endothermal peak	changing to gray
III	135–420 °C	reduced rate of mass loss	no event	changing to yellow
IV	420–540 °C	mass loss at increased rate	endothermal peak	brown
V	from 540 °C onwards	mass stabilizes (no more losses)	no peak or plateau	orange brown
