What Tiangang does

Beijing Tiangang Additives Co., Ltd. (北京天罡助剂有限责任公司) is a privately held Chinese specialty chemical manufacturer founded in 1991, focused exclusively on the development, production, and sale of anti-aging functional materials—principally hindered amine light stabilizers (HALS) and UV absorbers—used to extend the service life of polymers exposed to UV radiation. The company operates three integrated production bases in China (Daxing/Beijing, Gu'an/Hebei, and Cangzhou) with a combined design capacity exceeding 30,000 tons/year, and is described as one of Asia's largest integrated light stabilizer production complexes. Its proprietary product portfolio spans high-molecular-weight polymeric HALS (HS-944, HS-622, HS-770), acid-resistant grades for agricultural film (HS-625, T-68, T-69), low-alkalinity HALS for engineering plastics (HS-778), next-generation triazine UV absorbers (UV-570, UV-630), and complementary antioxidants (AO series).

Tiangang generates revenue by selling specialty chemical additives directly to B2B polymer manufacturers, agricultural film producers, automotive parts suppliers, coating companies, and textile manufacturers via direct enterprise sales, with approximately 50% of production exported to over 50 countries through its wholly owned Belgian sales subsidiary (Tiangang Chemicals Europe B.V.). Pricing is quote-based and not publicly disclosed, with contracts typically running multi-year. The company holds a dominant >70% share in China's agricultural film light stabilizer market, supplies acid-resistant formulations tailored to China's pesticide-heavy farming environments, and is expanding into higher-value engineering plastics and automotive applications. A joint venture with Swiss Clariant in the Cangzhou national-level chemical park extends its reach into high-end polymer additives for international customers.

The company holds 6+ granted invention patents with independent CAS registrations for core chemical structures, invests over 4% of sales in R&D, and operates national-level engineering research centers for plastic weather resistance technology. It is certified under ISO9001, REACH, and RoHS, has been designated a National-level "Little Giant" specialized enterprise by China's MIIT, and participates in national standards-setting for polymer aging methods (SAC/TC15/CS5). Management is led by Chairman Liu Jie (刘杰) and General Manager Li Yuqing (李玉庆), with no disclosed external equity investors.
