The reason why ultraviolet absorbers can absorb ultraviolet light is that the molecules of such compounds contain the structure of conjugated π electron system and the structure that can carry out the movement of hydrogen atoms. Some only have the first part.

Light stabilizer is polymer products (such as plastic, rubber, coating, synthetic fiber) of a kind of additive, it can block or absorb ultraviolet energy, quenching singlet oxygen and hydrogen peroxide into the active substances, and other functions, make the polymer under the radiation of light, can eliminate or reduce possibility of photochemical reaction, prevent or delay the aging process, light So as to achieve the purpose of prolonging the service life of polymer products.

High efficiency antioxidant for PE materials, especially for PE cables and resins
