CeO2 has 4F1 electron configuration with its nano-meter particle size. So it is very sensitive and strong for ultraviolet absorbed and harmless for environment. Widely used in paint, plastic, fiber, rubber, anti-sunlight cosmetics. The ultraviolet light is a major cause of aging for organic polymer. The plastic or other polymer products with such material feature good resistance to light aging and extended life. Presently, the organic light stabilizers have some shortage of short life and toxicity. |
