Introduction：
UV-1600 is an ultraviolet light absorber (UVA) of thehydroxyphenyl triazine class exhibiting very low volatility, high absorption and good compatibility with a variety of polymers, does not affect transparency and coloring. 。“Low volatility、High absorption of UVA、Resistant to high temperature、Light colored transparency” is the four major features。UV-1600 allows polycarbonates、polyesters、PMMA and acrylics to achieve a higher resistance to weathering than conventional UV Absorbers. And the dosage of UV-1600 is much lower, therefore, UV-1600 is reputed as “Setting a new benchmark for the industry in terms of durability, long-term weather resistance.” UV-1600 surpass most UV Absorbers on the market。
Applications：
UV-1600 is suitable for all kinds of high performance polymers and alloys, such as PET、PBT、PC(linear and branched), polyether ester, PMMA, acrylic copolymers, PA、PS、SAN、ASA, polyolefin, etc., reinforced or not reinforced, filled or unfilled, flame-retardant or non-flame-retardant, transparent, translucent, etc. 
Especially suitable for:
1）PC film, sheet, board and so on, good compatibility with PC, low volatility in high temperature melt processing, not easy to precipitate, do not need to wash the runner and mold.。
2）Nylon（PA）film、sheet、board，etc.
3）PET、PBT film、sheet、board，etc.
4) PMMA film、sheet、board，etc
5) Other applications with special requirements for long-term light stability。
