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.
