UV Absorbers
UV absorbers act by absorbing the UV radiation and dissipating the resulting energy in a non-
photosensitizing way, such as heat, by intramolecular proton transfer.

DESCRIPTION
PRODUCT DETAIL
GC THT 4611-2 blend
It’s a complex and high efficiency light stabilizer for the following products: polyolephines, TPO, TPE, TPR. Suitable for NOT FOOD plastic packaging, mainly for sport&leisure applications.
GC UVS 3638
It has a very strong coverage of UVA and UVB coverage, no colour and imparts excellent UV protection for PC, PET and co-polyesters.
It is typically used in the stabilization of PET bottles and electronic displays.
GC DMBA RL-1000
It is a photoselective additive for plastic agricultural applications such as covers that helps improve crop (raccolto) quality and productivity. It is a red luminescent additive for agricultural films, shifts or converts light from the UV part of the spectrum to visible light used by crops for photosynthesis. It can boost growth of certain flowers like roses, which can produce higher yields compared with a conventional PE film and shorter growing cycles.
The additive is designed to transform plastic films used in this industry from a simple cover to a sophisticated and active part of the crop growing process
GC UV 161 PWB
It is our alternative of GC UV 326: this is a light stabilizer blend that shows excellent UV stabilization with minimal impact on color.
GC UV 326
2-(5-Chloro-2H-benzotriazol-2-yl)-6-(1,1-dimethylethyl)-4-methylphenol
CAS n. 3896-11-5
PHYSICAL FORM: GR, PW
It is suitable for polymers processed at high temperatures.
GC UV 571
A mixture of: isomers of 2-(2H-benzotriazol-2-yl)-4-methyl-(n)-dodecylphenol; isomers of 2-(2H benzotriazol-2-yl)-4-methyl-(n)-tetracosylphenol; isomers of 2-(2H-benzotriazol-2-yl)-4-methyl-5,6-didodecyl-phenol. n=5 or 6
PHYSICAL FORM: LIQ
It is an effective light stabilizer for a variety of polymers. It protects polymers from UV radiation, helping to preserve the original appearance and physical integrity of molded articles, films, sheets and fibers during outdoor weathering. GC UV 571 can be used alone or in combination with other additives and it is liquid.
