Rheology of Thermoplastic Polymers Using Parallel Plates An example of polyethylene analyzed in the temperature range of 160 to 220°C is shown in the figure. Frequency sweep measurements were conducted at multiple temperatures within the experimental range of 0.06 to 628 rad/s. Time-Temperature Superposition (TTS) was used to extend the data to high or low frequencies and to create a master curve at a permanent reference temperature for applications.

Rheology of Solid Polymers Using a Torsion Clamp In the ETC oven, viscoelastic property analysis can be performed on solid samples up to 13mm (width) × 50mm (length) × 5mm (thickness). The figure shows an analysis example where a solid ABS sample was subjected to vibrational measurement with a temperature scan from -160°C to 200°C at a rate of 3°C/min. The size and shape of these parameters also depend on characteristics and composition such as crystallinity, orientation, fillers, and crosslinking density.
