Standard Test Method for Thermoplastic Elastomers—Measurement of Polymer Melt Rheological Properties and Congealed Dynamic Properties Using Rotorless Shear Rheometers

Importancia y uso:

5.1 This test method is used to measure viscoelastic properties of thermoplastic elastomer polymer melts at elevated temperatures as well as the dynamic properties of the respective congealed thermoplastic elastomer specimens measured at lower temperatures. These polymer melt viscoelastic properties may relate to factory processing behavior while the dynamic properties of the respective congealed specimen may relate to product performance.

5.2 This test method may be used for quality control in thermoplastic elastomer manufacturing processes, for quality control of received shipments of thermoplastic elastomers, and for research and development testing of thermoplastic elastomers. This method may also be used for evaluating processing and product performance differences resulting from the use of different compounding materials and process conditions in the making of these thermoplastic elastomers.
