What Rianlon does

Rianlon Corporation is a Tianjin, China-headquartered specialty chemicals platform that develops, manufactures, and sells anti-aging additives and application technologies for polymer materials. Founded in 2003 and listed on the Shenzhen Stock Exchange (szse:300596) in 2017, it is the first Chinese A-share listed company in the polymer anti-aging industry. Its core technology stack comprises primary and secondary antioxidants under the RIANOX brand, UV absorbers and hindered amine light stabilizers (HALS) under the RIASORB brand, and customized integrated stabilization packages under the U-pack brand. The product portfolio serves customers in automotive, agriculture, coatings, engineering plastics, renewable energy, building and construction, packaging, electronics, and personal care, with sales in 60+ countries.

The business operates through three strategic pillars articulated as the 'Three Life Curves': anti-aging additives (core), lubricant additives via the Jinzhou Kangtai subsidiary (growth), and biomanufacturing/synthetic biology plus polyimide films via the Aegis brand, Life Sciences Division, and Yixing Chuangju Electronic Materials (future growth). Rianlon runs six production bases in China with a dual-base backup system, 3,000 MT/A capacity for RIANOX 330 (making it the world's largest producer of that molecule), and a 72-hour global supply chain. Distribution is enterprise-direct via regional sales offices in Hong Kong, the Americas (Staten Island), Germany (Düsseldorf), Japan, and the Middle East (Dubai).

Revenue is generated primarily through B2B enterprise sales of specialty chemicals on quote-based commercial terms, with no public pricing and an e-commerce channel (e.rianlon.com) for select products. Long-tenured strategic relationships — including a 17-year partnership with Kingfa, Phase III cooperation with Wanhua Chemical, and a strategic framework agreement with Infineum — anchor demand. The company employs 501–1,000 people, including 300+ R&D professionals, and holds 300+ patents as of December 2025. EcoVadis Gold Medal status (top 5% globally in both 2024 and 2026) and UN Global Compact membership since 2021 support procurement-gate qualification with multinational customers.
