It is important to have a deep knowledge of a material’s formulation to understand the degradation mechanisms taking place when the materials are exposed to external stresses. In the last years, cracking of backsheets with polyvinylidene fluoride (PVDF) has become an issue. PVDF based backsheets are widely used, but there is still quite some uncertainty regarding their exact formulation and the mechanisms behind the degradation. In this study seven PVDF films were investigated to get a deeper knowledge regarding their formulations and their principal properties.
