Resumo
Thermoplastic materials are sensitive to ultraviolet radiation (UV), which
can cause structural changes, causing variation in mechanical properties and
appearance. UV range between 250 and 400 nm is considered the most aggressive
to polymers, and prolonged exposure to it results in breakage and/or crosslinking
chains. Light stabilizer additives, blockers or absorbers are added to the polymers
for protection in order to extend the life of the final product. The choice of the
adequate light stabilizer additive system depends on factors such as resin final
application, thickness, geographic location of exposure, presence of fillers in the
composition, contact with chemicals, among others. This study evaluates different
additive systems: conventional organic, inorganic nanotechnologyc base and the
synergy between them when applied to polyethylene considering carbonyl index
and UV/VIS results after aging by QUV chamber.
