Core Viewpoint - The light stabilizer industry in China is experiencing significant growth due to the increasing demand from various sectors such as plastics, coatings, and rubber, driven by the country's robust manufacturing base. The market is projected to expand further in the coming years, with a notable increase in both demand and market size [1][4][7]. Industry Definition and Characteristics - Light stabilizers are chemical substances that inhibit or reduce the degradation of polymer materials caused by light exposure, enhancing their light resistance. They can be categorized based on their mechanisms of action, including radical scavengers (mainly hindered amine light stabilizers, HALS), ultraviolet absorbers (UVA), and quenchers [1]. Current Development Status - The global market for light stabilizers has shown steady growth, with the market size increasing from $2.021 billion in 2016 to $2.640 billion in 2020, and reaching $3.755 billion in 2022. However, it decreased to $2.987 billion in 2023 before rebounding to $3.363 billion in 2024. Asia remains the largest consumer region, accounting for 55.07% of the global market in 2024 [5][9]. Market Size and Demand - In China, the demand for light stabilizers is expected to reach 162,400 tons in 2024, with a market size of 7.925 billion yuan. The demand is projected to grow to 173,000 tons and a market size of 8.148 billion yuan by 2025. The plastic sector is the largest consumer, followed by coatings and chemical fibers [9][18]. Industry Chain - The light stabilizer industry chain consists of upstream raw materials, including alkyl phenols, fatty ketones, and aromatic amines, which directly affect the performance and quality of light stabilizers. The midstream involves manufacturers, while the downstream applications primarily include plastics, chemical fibers, rubber, and coatings [11]. Development History - The light stabilizer industry in China began in the 1970s and has evolved through various stages, including technological accumulation, industrial breakthroughs, and structural optimization, forming a complete industrial system driven by technological innovation and market demand [13]. Competitive Landscape - The Chinese light stabilizer industry is characterized by a relatively fragmented competitive landscape, with no dominant players. Major companies include Suqian Liansheng, Yuanli Technology, and Lianlong, with Suqian Liansheng leading in production capacity at 37,100 tons [15][16][18]. Future Trends - The research and development of new, efficient light stabilizers are gaining attention, with trends focusing on high molecular weight, composite materials, and reactivity. The continuous demand from downstream industries and ongoing technological innovations are expected to drive the growth of the light stabilizer industry in China [23].
