TPE-E, Ester-Based Thermoplastic Elastomer

Sample

Hytrel HTR 8105 BK as pellets

Conditions

Measuring cell: DSC20

Pan: Aluminum standard 40 µl, pierced lid

Sample preparation: Disk cut from pellet, 7.3 mg

DSC measurement: Heating from 30 to 250 °C at 20 K/min

Atmosphere: Nitrogen, 50 cm³/min

Evaluation

The spline baseline type was used. It fits the c_p temperature function before and after the peaks very well. 

Conclusions

TPE gives characteristic DSC curves that can be used for identification purposes. Low temperature DSC (-100 °C) would have to be used to characterize the elastomeric behavior of the soft segments.
