Beijing Tiangang Auxiliary Co., Ltd. is a national high-tech enterprise dedicated to the R&D and production of high-performance polymer additives. As one of the earliest companies in China to specialize in anti-ageing functional materials, Tiangang holds a strong reputation in both domestic and international markets and leads several key segments. Our products are exported to Europe, North America and Asia and are specified by many internationally renowned companies.
The group employs more than 400 people across three modern production and R&D sites: Daxing District, Beijing (67,000 m² / 100 mu); the Cangzhou National Lingang Economic and Technological Development Zone (200,000 m² / 300 mu); and Gu'an County, Hebei Province (100,000 m² / 150 mu). Combined annual capacity for light stabilizers and intermediates exceeds 30,000 tonnes, making Tiangang a major integrated light stabilizer production base in Asia. Production is fully DCS-controlled and run under lean manufacturing to ensure consistent quality. Tiangang Chemicals Europe B.V. in Brussels, Belgium serves overseas customers, and a joint-venture plant with Clariant in Cangzhou produces high-end chemical additives.
Tiangang has been recognized as a National High-Tech Enterprise and a national-level “Little Giant” specialized and innovative enterprise. The company owns a portfolio of proprietary products and invention patents. Its R&D center is certified by the Beijing Municipal Bureau of Economy and Information Technology as a Beijing Enterprise Technology Center (provincial level). Its weathering laboratory has been named “China Light Industry Plastics Weathering Engineering Technology Research Center” by the China National Light Industry Council and “China Plastics Weathering Technology Laboratory” by the China Plastics Processing Industry Association — one of the very few key laboratories in China holding both distinctions and focused exclusively on material weathering and anti-ageing research.
