Tensile test on coating films using a Universal Extensional- Fixture (UXF) with an MCR

Extensional testing methods with a controlled tension play an important role when selecting a material for a specific application and/or performing quality control procedures. The tests in this report are performed in order to determine the mechanical coating strength, which provides information about the inter particle bonding.

Extensional testing methods with a controlled tension plan an important role when selecting a material for a specific application and/or performing quality control procedures. The tests in this report are performed in order to determine the mechanical coating strength, which provides information about the inter particle bonding. The Universal Extensional Fixture (UXF) is used for tension measurements on thin films and fibers. In combination with a Modular Compact Rheometer (MCR) and a Convection Temperature Device (CTD), the UXF enables tensile strain- or stress-controlled DMA tests across a wide (-150 to 270 °C) temperature range. This combined system is used to investigate effects such as temperature-related stability, shrinkage, elongation, crystallization, phase transition, relaxation and brittleness. Beside DMA tests, the UXF system can be used for tensile tests on films and fibers. This is one of the most widely used methods for characterizing the mechanical properties of films. Using this test method, the sample is loaded by a constant strain rate until either a certain stress/strain value is reached or the sample breaks.
