Cathay Biotech Inc. is a listed company on the Shanghai stock exchange’s STAR market (symbol: 688065.SH). Cathay Biotech was founded in 2000 and engages in the research, development, production and sales of new bio-based materials based on synthetic biology and other disciplines and utilizes bio-manufacturing technology. Its headquarters and R&D center are located in the Zhangjiang Hi-Tech park in Shanghai and the two production sites are in Jinxiang and Wusu, P.R.China. The third production site is in construction process in Taiyuan, also in China, which will expand the capacity of current 75kt/a long-chain diacids, 50kt/a pentanediamine and 100kt bio-based polyamides to much larger scale.

As a company focused on the polyamide industry chain, Cathay Biotech produces monomer raw materials that can be used in the production of bio-based polyamides, including a series of bio-manufactured long-chain diacids and bio-based pentamethylene diamine, as well as several bio-based polyamides and related products. The products are used in many applications in textiles, pharmaceuticals, perfumes, automobiles, electronic appliances, consumer goods and other fields.

Cathay Biotech is the leading supplier of bio-manufactured long-chain diacids worldwide. In 2018, Cathay’s long-chain diacids were rated as the individual champion product of the manufacturing industry by the Ministry of Industry and Information Technology and the China Federation of Industrial Economics.

Pentamethylene diamine (PDA), produced from sustainable resources through Cathay’s proprietary process, can be widely used as an epoxy curing agent, an ingredient in hot melt adhesive formulations, diisocyanates and in other related applications. The substitution of hexamethylene diamine (HMDA) by Cathay’s PDA in the field of polyamides can solve the main bottleneck of the development of the domestic polyamide industry. Cathay’s PDA also provides the market and customers with new "biological manufacturing" materials made from renewable biomass raw materials. Moreover, PDA provides downstream bio-based polyamides and other products with excellent performance characteristics due to its odd-numbered carbon structure.

Cathay’s array of bio-based polyamide products, which are polymerized from the proprietary bio-based PDA and different diacids, have many excellent characteristics such as flame retardance, moisture absorption, easy dyeing, low warpage and high flowability, as well as the advantages of sustainable sourcing and low environmental impact. Based on its own bio-based polyamide products, Cathay launched the high-performance textile material TERRYL^® for broad applications in clothing, carpets, industrial yarns and other textile fields. Based on the excellent properties such as high strength, high heat resistance and good dimensional stability, Cathay launched the engineering material ECOPENT^®, which is used in automotive applications, electronics and electricals, industrial and consumer goods and other engineering material fields, and provides solutions for the sustainable development of our society.

Cathay Biotech will continue to promote the innovation of bio-based products and technologies based on our four core technologies, and to provide a positive force for the development of synthetic biology and bio-manufacturing to lead the sustainable development of technologies and industries.
