Light stabilizer is an assistant to improve the light stability of polymer materials.
Ultraviolet absorber is one of the product types with wide application range and large demand. It has the ability to absorb ultraviolet rays in sunlight and fluorescent light source, and also has the characteristics of good chemical stability, good thermal stability, not easy to decompose, not easy to change color, non-toxic, tasteless, insoluble or insoluble in water, Adding it to polymer materials can protect its properties from UV damage.
The absorption of ultraviolet rays by polymer materials will cause oxidation and degradation reactions, resulting in the decline of product performance and service life.
Ultraviolet absorber is a preventive light stabilizer, which can convert ultraviolet rays into harmless heat and fluorescence release, reduce the destructive effect of ultraviolet rays on polymer materials, and achieve the protective effect. UV absorbers mainly include benzophenones, benzotriazoles, salicylates, substituted acrylonitrile, triazines, etc. among them, benzophenones and benzotriazoles are widely used in the industrial field.
UV absorbers can be used in the production of plastics, rubber, coatings and other products.
They are highly irreplaceable, and the global market demand continues to grow. From 2015 to 2020, the annual compound growth rate of the global market demand for light stabilizers was, and the market demand in 2020 was about 10000 tons. As one of the important subdivisions of light stabilizers, the global market demand for UV absorbers continues to rise. Among them, North America, Western Europe, China, Japan and other countries and regions are the main demand markets.
Specifically, in the North American light stabilizer Market, the market share of ultraviolet absorber accounts for about 42%; In the Western European market, the market share of ultraviolet absorber is about 28%; In the Japanese market, the market share of ultraviolet absorbent is about 48%; In the Chinese market, the market share of ultraviolet absorbent accounts for about 39%. Among them, the development time of China's polymer material industry is relatively short, and the market growth is relatively rapid at this stage. Therefore, the demand for ultraviolet absorbent is growing relatively fast.
The global UV absorber manufacturers are mainly distributed in Western Europe, China, Japan and other countries and regions. The representative enterprises include BASF of Germany, Sabo of Italy, Solvay of Belgium, Clariant of Switzerland, adico of Japan, Songyuan of Japan, MPI of the United States and other foreign enterprises, as well as Raytop chemical, Lyon, Weihai Jinwei, Kerun new materials, Tisheng technology, fubia chemical Tiangang additives, Liansheng technology and other domestic enterprises.
In the global market, UV absorbers are the second largest category of light stabilizers after hindered amine light stabilizers, and the demand continues to grow.
China's economic growth is transforming from high speed to high quality, and most of the product markets of polymer materials are increasingly saturated, and the demand growth of ultraviolet absorbent will gradually slow down. However, with the development of high-tech industry, the demand for high-performance polymer materials is rising, which will drive the growth of market demand for high-end ultraviolet absorbent. From this point of view, the development prospect of China's ultraviolet absorbent industry is good.
