Rheotens Melt Elasticity
Test ID
R-019
Description
This test measures the melt elasticity and tensile strength of a material at a particular temperature. The sample, dried if needed, is loaded into a preheated test barrel of a capillary rheometer. The extrudate is drawn in tension by the wheels of the Rheotens apparatus; the drawing force is measured at a constant rate of acceleration until break.
