Omnistab UV 360
Omnistab UV 360 is a chemically phenol, 2, 2-methylene-bis (6-(2H-benzotriazol-2-yl)-4-(1, 1, 3, 3-tetramethylbutyl)) grade. Acts as an UV absorber. It is a very low volatile product of hydroxyphenyl benzotriazole class, imparting outstanding light stability to a variety of polymers. Particularly suitable for processing and aging conditions where high loads and good compatibility are required. Helps to achieve high UV screen performance and minimizes sublimation through vents as well as prevention of deposits on molds, chill rolls or calibrators.
Also suitable for complex moldings, fibers, sheets, twin wall sheets, thin films and laminated or co-extruded semi-finished articles. Compatible with acrylic resins, polyalkylene terephthalates, polycarbonates, modified polyphenylene ether or sulfide compounds, polyamides, polyacetals, styrenics, elastomers and various high performance plastics. Omnistab UV 360 (0.2-10% by weight) can be readily incorporated in the polymer by using conventional techniques such as powder, solution, or melt blending such as extrusion compounding.
Omnistab UV 329
Omnistab UV 329 is chemically 2 Phenol, 2-(2H-benzotriazol-2-yl)-4-(1, 1, 3, 3-tetramethylbutyl) grade. It acts as a UV absorber belonging to hydroxyphenyl benzotriazole class.
It is an effective light stabilizer for a variety of plastics and other organic substrates. Protects polymers from UV radiation, helping to preserve the original appearance and physical integrity of molded articles, films, sheets, and fibers during outdoor weathering. Use levels of Omnistab UV 329 ranges between 0.1 and 1.0%, depending on substrate and performance requirements of the final application.
Omnistab UV 327
Omnistab UV 327 acts as an ultraviolet light absorber. Is a strong absorber of ultraviolet radiation in the 290~400nm region and has a high degree of photostability-photochemical energy absorbed in the ultraviolet region is dissipated as thermal energy. Exhibits good initial color, low volatility, excellent stability to heat as well as light, superior wash fastness, and resistance to gas fading.
The low pKa and high hindrance of the phenolic group result in low sensitivity to metal containing ingredients in polymer formulation – catalysts residues, metallic driers, etc. It can be used in combination with phenolic & phosphite antioxidants, and HALS to optimize performance in outdoor use. It is particulary suitable for polypropylene and polyethylene as well as cold cured polyesters, polyurethanes.
Omnistab UV 234
Omnistab UV 234 is chemically phenol, 2-(2H-benzotriazol-2-yl)-4,6-bis(1-methyl-1-phenylethyl) grade. Acts as a UV absorber. It is a high molecular weight product belonging to hydroxyphenyl benzotriazole class. Imparts excellent light stability to a variety of polymers. Features low volatility, exceptional light absorbing characteristics and good compatibility in various substrates.
Omnistab UV 1577
Omnistab UV 1577 is a hydroxyphenyl triazine grade. Acts as a UV absorber. Exhibits very low volatility and good compatibility with a variety of polymers, co-additives and resin compositions. Allows polycarbonates and polyesters to achieve a higher resistance to weathering than conventional benzotriazole UV absorbers. Suitable for polyalkene terephthalates & naphthalates, linear and branched polycarbonates, modified polyphenylene ether compounds, and various high performance plastics.
Omnistab UV 1164
Omnistab UV 1164 is a 2-(4,6-Bis-(2,4-dimethylphenyl)-1,3,5-triazin-2-yl)-5-(octyloxy)-phenol. It acts as an ultraviolet light absorber. It offers low volatility.
