DSC/ thermal analysis: determination of glass transission temperature
In the region of glass transition temperature, there is a sudden change in the heat capacity cp, what with a sudden change in the physical and technological properties is usually accompanied. So some polymers are below the glass transition temperature suddenly hard and fragile (for example PP), others can be thermoformed very well when exceeding the glass transition temperature (for example PET). The measurement by DSC is very smart, but not feasible at all polymers. We are happy to advise you.
