Profile

Cathay Biotech (SSE 688065) is a high-tech enterprise specializing in synthetic biology and bio-manufacturing to produce bio-based materials. Founded in 2000 and headquartered in Shanghai, the company is a global leader in bio-based long-chain dicarboxylic acids (DC10-DC18) and bio-based pentamethylene diamine. Its core products include these monomers, bio-based polyamides (marketed as TERRYL and ECOPENT), and bio-based piperidine.

As of 2026, the company remains active and is transitioning from a standalone material supplier to a broader polymer giant. In 2025, it achieved 3.295 billion yuan in revenue. Production capacity for long-chain dicarboxylic acids reached 115,000 tons annually, with sales exceeding 100,000 tons. While long-chain acids remain its primary revenue driver, the company is scaling its bio-based polyamide and composite material business, with new production lines in Hefei entering the equipment debugging phase. Major strategic developments include a 5.915 billion yuan private placement to fund expansion and ongoing construction of a large-scale production facility in Taiyuan, expected to be completed by 2027.
