2-(2′-Hydroxy-5′-Methyl-Phenyl)Benzotriazole /Drometrizole with Cas 2440-22-4
What is 2-(2′-Hydroxy-5′-Methyl-Phenyl)Benzotriazole?
(2′-Hydroxy-5′-Methyl-Phenyl)Benzotriazole As a UV absorber, it is widely used in polyvinyl chloride, polystyrene, polycarbonate, polymethyl methacrylate, AS resin, ABS resin, polypropylene, and polyethylene. Can be used together with phenolic antioxidants and phosphite antioxidants.
Drometrizole is an absorbent that can efficiently absorb 290-400nm ultraviolet light, with low volatility and good thermal stability. This product hardly absorbs visible light, making it particularly suitable for colorless, transparent, and light colored products.
Feature:
1.Odorless and will not cause any odor to the polymer during use.
2.Not sensitive to metal ions.
3.Non flammable, non explosive, non-toxic, safe and harmless to use.
4.Good photographic stability and strong absorption of ultraviolet light.
5.Good thermal stability, suitable for plastic products that require high-temperature processing.
6.Almost does not absorb visible light, especially suitable for colorless, transparent, and light colored products.
Recommended Dosage:
- Polystyrene: 0.2-0.5wt%
- ABS resin: 0.3-0.5wt%
- High impact polystyrene: 0.5-2.0wt%
