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.

Antioxidants have been widely used in plastics and coatings ,especially in polyolefin, ABS , followed by POM, PVC and nylon. In order to obtain better benefits in using, more than two antioxidants should be fully used that can produce advantages of additive or synergistic effects.

Before introducing our products, we would like to have a brief introduction of polymer inhibitor--Polymerization inhibitor is an industrial additive, usually used to prevent the progress of polymerization.

Omnistab AN 1135 is an excellent antioxidant suitable for various polymers. It can be used for polyurethane soft foam rubber sheets to prevent the formation of peroxides during storage of polyols, and to prevent scorching during the foaming process.

Powder coating is a new kind of coating which does not contain organic solvent but exists in powder form and forms coating.

There are many factors affecting the weathering resistance of paint film in paint industry, among which sunlight radiation and oxygen in the atmosphere are the main factors affecting the aging of paint film.
