UV-absorbing agent UV-327 is an excellent benzotriazole UV absorber with the chemical name 2-(2'-hydroxy-3',5'-di-tert-butylphenyl)-5-chlorinated Benzotriazole, commercially available as a light yellow or white powder, is soluble in solvents such as styrene, benzene, and toluene. The absorption wavelength range is larger than the UV absorber UV-P, which can strongly absorb ultraviolet light of 300-400 mm, the highest absorption peak is 353 nm, and has good chemical stability, low volatility, good compatibility with polyolefin, and is especially suitable. In polyethylene (PE), polyvinyl chloride (PVC), polystyrene and polypropylene (PP), can also be used in polymethyl methacrylate, polyoxymethylene, unsaturated polyester, polymethyl methyl methacrylate , polyurethane, ABS resin, polypropylene fiber, paints, colorants, adhesives, candle wax and other polymers and many other fields. Low toxicity, non-flammable, non-corrosive, good storage stability, and a significant synergistic effect with the thioester antioxidant DLTDP (PS800).
1. High temperature resistance and good thermal stability.
2. Not sensitive to metal ions.
3, non-flammable, not explosive, non-toxic, safe and harmless to use.
4, almost no absorption of visible light, especially suitable for colorless transparent and light-colored products.
5, the camera stability is good, has a strong absorption of ultraviolet light.
6. It does not change yellow under alkaline conditions and is resistant to oil.
7, low volatility, less loss during processing.
8, good thermal stability, can be used for plastic products that require high temperature processing.
