With the destruction of the earth’s ozone layer more and more serious, the solar ultraviolet radiation on the earth is becoming intense. Therefore, UV absorber has become one of the essential additives for various polymer materials, skin protection supplies and so on.

Currently, Automobile coating is one of the fastest developing coating varieties, and its application in the field of coating is second only to architectural coating. According to the China Automobile Industry Association, in 2020, China sold 25.311 million cars,

Impacted by air pollution, the ozone layer is thinning and the amount of ultraviolet radiation reaching the surface gradually increases, and the shortwave of UV light trend is enhanced. Especially the medium and long wavelength UV Light(290-400nm) has caused great harm to human health, which lead to skin tanning, pigmentation, keratin growth and aging.

Nowadays China’s modern industry develops rapidly, many fields need damping materials with wide temperature range, high performance and intelligence, such as the military industry, the machinery industry, the construction industry, the emerging aerospace industry and the electronics industry.

Polyurethane foam plastic is a porous material composed of a large number of micro pores resin, and also called "PU foam". Polyurethane foam plastics account for more than 50% in the total amount of PU products, which is the most important variety.

Prolonged exposure to ultraviolet light can cause skin to age, due to its higher radiation energy, The ultraviolet rays in the UV-B can burn the skin, producing dark spots, and even lead to skin cancer.

On December 30, 2020, Novel Coronavirus vaccine of Sinopharm Beijing Co., Ltd. was approved by the State Food and Drug Administration (SFDA) and marketed with conditions.

​After long-term exposure to ultraviolet ray, it will cause the autoxidation of polymer materials, which will lead to the degradation of polymer, make the products become discolored, brittle and performance reduction, so as to lose its using value, this process is called Photooxidative aging.

​Triazines UV absorbers not only have excellent properties, but also have little impact on the ecological environment during their use.
