TINUVIN 329 (Plastics)
TINUVIN 329 (Plastics)
Tinuvin 329 is an ultraviolet light absorber (UVA) of the hydroxyphenyl benzotriazole class, which is used as a light stabilizer for plastics and other organic substrates.
The use levels of Tinuvin 329 range between 0.1 and 1.0 %, depending on substrate and performance requirements of the final application. The product can be used alone or in combination with other additives such as light stabilizers (hindered amines), antioxidants (hindered phenols, phosphites, thiosynergists, hydroxylamines), and other functional stabilizers and additives. The use of Tinuvin 329 in combination with hindered amine light stabilizers is particularly noteworthy in that a synergistic performance is often observed. Performance data of Tinuvin 329 alone or in combination with other additives are available in selected substrates.
Applications
This product is an effective light stabilizer for a variety of plastics and other organic substrates.
Features & Benefits
Tinuvin 329 protects polymers from UV radiation, helping to preserve the original appearance and physical integrity of molded articles, films, sheets, and fibers during outdoor weathering.
