The side effects of UV light stabilizer on properties of polypropylene based composite tape yarn

Abstract

Initial consuming properties of polypropylene (PP) based composite tape yarns having different portions of ultraviolet (UV) light stabilizer are studied. In many cases, the samples with different portions of UV light stabilizer exhibit changes at level of initial properties, that is, the statistically significant side effects are obtained. When portion of the additive increases, the initial values of width, thickness and linear density of the modified samples are found to be reduced. The additions of UV light stabilizer also generate the statistically significant changes for the most tensile characteristics. The linear and second order polynomial equations are suggested to show the side effects on the properties. Some visual changes in morphology, that is, the differences in smoothness of the surfaces of the samples are also noticed. © 2016 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2017, 134, 44400.

Chemical degradation and failure analyses by acoustic emission of PP/EOC blends exposed to ultraviolet radiation

“…Under these conditions, the use of photo stabilizers additives such as ultraviolet absorber (UVA) or hindered amine light stabilizer (HALS) is considered mandatory to prolong the lifetime of PP based products. [3] These two types of additives act under different mechanisms and, when combined, can achieve a higher efficiency. [4] It is very important to monitor the estate of PP deterioration under ultraviolet exposure in an attempt to prevent catastrophic failure of products, and this is normally done using conventional techniques like mechanical properties, infrared spectroscopy, and measurements of molar mass.…”
