Tinuvin® 1600 is an ultraviolet light absorber (UVA) of the hydroxyphenyl triazine class exhibiting very low volatility, high absorption and good compatibility with a variety of polymers, co-additives and resin compositions. Tinuvin 1600 allows polycarbonates, polyesters, and acrylics to achieve a higher resistance to weathering than conventional hydroxyphenyl triazine, benzotriazole or cyanoacrylate UV absorbers.

Applications

Applications include polyalkene terephthalates and naphthalates, linear and branched polycarbonates, acrylics (PMMA) and their copolymers, modified polyphenylene ether compounds, various high performance plastics, PA, SAN, ASA, as well as polyolefins.

The use of Tinuvin 1600 is indicated in polymer blends & alloys, such as PC/ABS, PC/PBT, PPE/IPS, PPE/PA and copolymers as well as in reinforced, filled and/or flame retarded compounds, which can be transparent, translucent and/or pigmented.

Features & Benefits

Due to its very low volatility, excellent thermal stability and high extinction coefficient, Tinuvin 1600 is particularly suitable for processing and aging conditions where high loadings, very good compatibility, and outstanding durability are required. Such requirements are especially critical for thin layers and films in general, e.g. extruded or co-extruded articles such as plain, multi-wall and corrugated sheets, oriented and biaxially oriented thin films, co-extruded or co-injected semi-finished parts, fibers and complex moldings.

Thanks to the high compatibility with polycarbonate combined with its extremely low volatility Tinuvin 1600 can be used in caplayer compounds avoiding plate-out, contributing to less frequent cleaning during extrusion. Moreover, its very high UV screening activity allows the use of lower concentrations than with traditional UV absorbers. This may be of particular importance when using Tinuvin 1600 in applications requiring high concentrations of UV absorbers. It also offers the opportunity to extend the service life of end-use articles.
