Continuous temperature & (flow regulation) with accuracy to 1/10th of a ℃. Swiss manufacture provides reliability, safety & fast ROI. WebDSC is a useful tool for studying this phenomenon known as “physical aging”. The initial DSC heating scan of physically aged polymers commonly reveals an endothermic peak near the trailing edge of the Tg step-change. This peak is referred to as the “enthalpy of relaxation” or “enthalpic recovery” (ΔH R ).
