Detecting Weak Glass Transition (Tg) in Polymers by HyperDSC
29 May 2012This note shows that HyperDSC, which employs heating rates of approximately an order of magnitude faster than traditional DSC, makes it possible to detect some challenging weak glass transitions, such as that of HDPE. The very quick response of the double-furnace power compensation DSC also makes the measurement feasible with the liquid nitrogen cooling accessory.

Thermal Analysis EquipmentThermal analysis equipment is used for measuring heat flow, weight loss, dimension changes or thermomechanical properties and is important for analyzing a material’s performance and stability. Thermal analysis equipment includes differential scanning calorimeters (DSC), thermogravimetric analyzers (TGA), thermomechanical analyzers (TMA), dilatometers, thermometers, vapor sorption analyzers, boiling and melting point apparatus. Thermal analyzers can reveal properties such as melting, crystallization and glass transitions or other processes such as oxidation, decomposition, volatilization, as well as coefficients of thermal expansion and modulus.
