Beijing Tiangang Auxiliary Wins China Light Industry Federation "Second Prize of Scientific and Technological Progress"

  As a leading enterprise in China's polymer material anti-aging light stabilizer additive field, Beijing Tiangang Auxiliary Co., Ltd.'s project "Development and Application of High-Efficiency, Low-Basicity, Polymeric Hindered Amine Light Stabilizer HS-625" won the China National Light Industry Council's 2020 "Second Prize of Scientific and Technological Progress." This is another provincial/ministerial-level scientific-progress award for Tiangang's technical research team after winning the Ministry of Education's "First Prize of Scientific and Technological Progress" in 2015.

  For more than twenty years, Tiangang has consistently upheld the concept of independent innovation, devoted to the R&D and application of new light stabilizers, and successively launched a number of high-level new auxiliary products with independent intellectual property rights, winning multiple scientific-progress and patent-related awards. The award-winning "high-efficiency, low-basicity, polymeric light stabilizer HS-625" went through more than ten years—from molecular structure design and optimization, chemical synthesis, and industrial scale-up to meticulous customer application tests and market promotion—filling a gap in this product category. It is a new high-performance hindered amine light stabilizer with a completely new chemical structure and granted invention patent protection.

    The development of HS-625 aimed to overcome the insufficient long-term performance of existing light stabilizers under harsh conditions and their susceptibility to failure when exposed to acidic substances. The product's effective piperidine groups adopt an N-alkylated structure, which has lower reactivity with acidic substances compared with conventional N-H hindered amine light stabilizers; through molecular structure optimization, the product's effective piperidine group content significantly exceeds that of similar products, so it shows superior performance especially under harsh conditions such as high temperature, high UV radiation, and long-term use. At the same time, the product adopts a long-chain structure and optimizes molecular weight and distribution, making it especially suitable for anti-aging use in high-performance films, flat yarns, and fibers with large specific surface areas; it features good compatibility, extraction resistance, and low bleed, with excellent long-term persistence. Meanwhile, the product is polymeric and thus safer and more environmentally friendly, having obtained certifications such as RoHS, REACH, U.S. TSCA, and FDA. It provides a better solution for the longevity of high-end, high-performance polymer new materials.

  Tiangang is committed to the R&D and industrialization of frontier polymer material technologies and will continue to strive to bring more high-performance, high-cost-performance technologies and products to the industry, promoting the transformation and upgrading from "Made in China" to "Created in China."

  Beijing Tiangang Auxiliary Co., Ltd. is a leading enterprise in China's light stabilizer product field, founded in 1991. It has long focused on R&D of polymer material weathering and anti-aging technology and the production of related additive products. Headquartered in Daxing District, Beijing, it has R&D centers and production bases in Gu'an County, Langfang City, Hebei Province, and the national-level chemical industrial park in Cangzhou. It is a national high-tech enterprise and a vice-chairman unit of the China Plastics Processing Industry Association. Tiangang's Beijing R&D center has been awarded "Beijing Municipal Enterprise Technology Center," as well as "China Light Industry Engineering Technology Research Center for Plastic Product Weathering" and "China Plastics Weathering Technology Laboratory," and has won the Ministry of Education's First Prize of Science and Technology Progress, and can assist customers with comprehensive weathering-related technology R&D evaluation and testing.
