"WebCrystallinity is a measurement of the degree of structural order of the molecules in a polymer. It has an inverse relationship with the permeability of polymer composites. The mass transfer of a gas or aroma in a semicrystalline polymer is primarily a function of the amorphous phase, resulting in the permeation of the gas or aroma. " - Crystallinity of denim

WebMay 25, 2024 · The results of density, differential scanning calorimetry (DSC) and X-ray diffraction (XRD) represent a decrease in the polymer’s crystallinity after deformation, which is more evident after three passes of ECAP. Moreover, a phenomenological mechanism is proposed to explain the variations of crystallinity after ECAP processing. WebOne of the most important properties of semi-crystalline thermoplastics (including PET, nylon, polyethylene, polypropylene, fluoro polymers, PES, PEEK) is the polymer’s percent crystallinity. This refers to the overall level of crystalline component in relationship to its amorphous component.
