Abstract

Degradation of polymeric materials is a well-known phenomenon in outdoor plastic applications. To avoid the damaging effect of the ultraviolet (UV) radiation nanosize fillers like ZnO can be utilized. Since ZnO can be considered to be photocatalytic, this activity is tried to suppress via coating of particles using various substances like silica, TiO2 and silane. Photo degradation limits the life-time of the material especially outdoor. In this work, we tested how coated nanoparticles (0.05 - 1.5 wt%) can be used as UV absorption agents in selected polypropylene matrixes. Material properties such as mechanical properties, absorption levels and chemical changes were tested before and after UV exposure. Tests were concluded with pilot scale processing tests.
