| | | This plot shows the thermal expansion of PE-LD as a function of temperature while being exposed to a dynamic load in comparison to the curve for the specific heat. The transitions from the pure elastic to the viscoelastic state and the increasing | | reduced amplitude of the square wave signal and the temperature of complete probe penetration for the PE-HD sample | | |
| | | penetration during melting onset are clearly shown in the TMA curve The good correlation between mechanical and energetic behavior is demonstrated by the comparison with the specific heat curve from a DSC measurement | | This curve comparison clearly depicts the difference in elasticity and melting temperature of PE-LD and PE-HD This is evident by the | | |
