Standard Test Method for Measurement of Percent Crystallinity of Polyetheretherketone (PEEK) Polymers by Means of Specular Reflectance Fourier Transform Infrared Spectroscopy (R-FTIR)

Importancia y uso:

4.1 Mechanical properties of PEEK polymers, such as stiffness or yield strength, are influenced by the level of crystallinity.5 The reported crystallinity index determined by this test method has been correlated with percent crystallinity in PEEK polymers by wide-angle X-ray scattering (WAXS) experiments.2, 3

4.2 This test method may be useful for both process development, process control, product development, and research.
