Currently commercialized bio-based polyamides include PA1010, PA11, PA610, PA410, among others, with multiple bio-based polyamides under development. Although bio-based polyamides account for less than 1% of the total polyamide production, research and industrialization of bio-based polyamides have drawn major chemical companies like DuPont, BASF, Arkema, DSM, LANXESS, EMS, Lanxess, and Evonik to plan and strategize.

Research on bio-based polyamides is closely following that of petrochemical-based polyamides. Using castor oil as the raw material, we have synthesized the fully bio-based polyamide PA11, which is now applied in the automotive industry, electronic appliances, pressure-resistant pipelines, sports equipment, food packaging, and water treatment. With the continuous development of the economy and the environment, bio-based polyamides have become a hot research topic in the materials industry.

Biobased nylon (PA66 modified, PA610, PA612, PA12, PA1010, PA1012, nylon modified, reinforced nylon, flame-retardant nylon) boasts excellent comprehensive properties, including mechanical strength, heat resistance, wear resistance, chemical resistance, and self-lubricity. It features a low coefficient of friction, has flame-retardant properties, is easy to process, and can be reinforced and modified with glass fiber and other fillers to enhance performance and expand its application scope.

Bio-based nylon plastics, including PA66 modified, PA610, PA612, PA12, PA1010, PA1012, nylon modified, reinforced nylon, and flame-retardant nylon, are developed based on polyphthalamide fibers. They are among the early thermoplastic plastics capable of bearing loads and are among the five major general-purpose engineering plastics, known for their high production volume, diverse varieties, and wide applications.

Polyamide (PA), commonly known as nylon, refers to a class of polymers with an amide group (-CONH-) in their molecular structure. Due to varying carbon-hydrocarbon structures and amide concentrations in the main chain, the structures and properties of polyamides differ significantly.
