Cathay Biotech produces bio-based polyamides using its proprietary bio-based PDA. The main raw materials for these products are renewable plant materials. Compared with the traditional petroleum-based polyamides invented in the 1920s, Cathay's bio-based polyamides are new bio-based materials which are environmentally friendly, have excellent performance, are more sustainable, and can be widely used in textiles and engineering materials. In 2014, Cathay realized a breakthrough in the industrialization technology of polyamides and completed the pilot plant test. A large-scale production line with an annual capacity of 100,000 tons will be operational in 2021.
Unlike the even-carbon structure of traditional petroleum-based products, Cathay's bio-based polyamides have an odd-numbered-carbon molecular structure which can yield excellent characteristics such as flame retardancy, moisture absorption, easy dyeing, low warpage, and high flowability etc.
Relying on its bio-based polyamide products, Cathay has launched TERRYL? for the textile industry, which is used in clothing, bags, carpets, work suits, tents and other textile downstream fields. TERRYL? was selected as the "New High Impact Fiber” on the textile market at the 2017 China International Textile & Yarn (Spring/Summer) Exhibition, and as the "China Fiber Fashion Leader" for two consecutive years. For the engineering materials industry, Cathay launched ECOPENT? for applications in automotives, electronics and electricals, cable ties, film and other engineering materials downstream fields. Both TERRYL? and ECOPENT? can replace nylon 66 or other nylon products made from hexylenediamine for various different applications.

Cathay's bio-based polyamide is made from renewable plant raw materials, which can effectively reduce carbon emissions compared to petrochemical-based counterparts. For example, the bio-based content has been analytically verified by a third-party qualified organisation, that the carbon emissions per unit of bio-based polyamide 56 can be reduced by half or more than half compared to traditional nylon.
