Effects of UV Stabilizers on Polypropylene Outdoors

Description: This article looks at hindered amine light stabilizers (HALSs) and nano ZnO were used to stabilize polypropylene (PP) film-based formulations that were exposed to ultraviolet (UV) light for different lengths of time, simulating the harsh outdoor weather of Dallas, Texas, USA. UV doses applied in our laboratory are 121 times larger than the UV dose provided by the sunlight in Texas. 15 different compositions were studied. The combination of HALSs and nano-ZnO stabilizers makes the PP films harde… more
