characterization tinuvin® xt 833 is a novel high performance light stabilizer system that imparts outstanding
weatherability to pvc and to pvc alloys. the primary advantage of tinuvin xt 833 over the
more traditional ultraviolet absorbers typically added to exterior pvc is the superior color and
physical property retention that it provides.
applications tinuvin xt 833 is a highly effective light stabilizer for pvc and alloys of pvc. its use is especially
recommended for applications like pvc roofing membranes, pvc pond, pool, and irrigation liners,
pvc coated fabrics such as those used in tents, tarps, and awnings, flexible pvc outdoor furniture,
pvc flooring, pvc automotive trim, and in other flexible pvc outdoor applications. it can also be
used in rigid pvc applications, especially those that do not contain tin mercaptide thermal
stabilizers. some of these applications include dark colored pvc siding and pigmented window
and door profiles. additionally, it can be used in pvc alloys like pvc/abs and pvc/pur in parts
exposed to sunlight.
features/benefits tinuvin xt 833 is a powerful ultraviolet light stabilizer that maintains its activity in highly acidic
environments. it protects pvc from the harmful effects of light exposure and helps it maintain its
initial appearance, its initial tensile, elongation, and impact properties and its physical integrity
during long-term weathering. in pvc roofing membranes, for example, it minimizes discoloration
and embrittlement and enables the membranes to retain their moisture barrier properties and their
reflectivity for many years. a similar appearance and physical property protection is provided by
tinuvin xt 833 in other outdoor pvc applications.
