The new energy automobile industry is expanding rapidly, and the three-power, thermal management and braking systems continue to iterate. Lightweight, high and low temperature resistance, chemical corrosion resistance, long-term aging resistance, multiple definable targets such as low carbon and environmental protection. The short board of traditional petroleum-based PA12 and other long chain polyamide materials is becoming increasingly prominent: the mechanical properties of 125 ℃ high temperature environment have dropped sharply, the low temperature toughness is weak, the raw materials are subject to the oil industry chain, the carbon emissions are high, and the stability of the supply chain is difficult to guarantee, it is difficult to adapt to the harsh working conditions of the new generation of vehicle.

The double carbon policy has been implemented and the global carbon control standards have been continuously tightened. Vehicle factories and first-class component suppliers have accelerated the layout of low-carbon material selection. Bio-based new materials with high performance and low-carbon attributes throughout the life cycle have become the industry's new needs, considering product reliability and green production, it has become the core problem of automobile pipeline research and development.

As the world's leading synthetic biology and biological manufacturing enterprise, Shanghai Kaisai Biotechnology Co., Ltd. has realized the autonomous and controllable whole chain from monomer synthesis, material modification to terminal application. Relying on the self-developed biological method long chain dibasic acid (DC9-DC18 full carbon chain) and biylpentanediamine core monomer, Kaisai biological launched BIOSYNAMID®Series of ultra-long carbon chain polyamides, whose bio-based content can reach 50% ~ 100%, have brought disruptive alternatives to the thermal management system of new energy vehicles.

The overall performance of thermoplastic automobile pipelines prepared by this material is better than that of mainstream long chain polyamide products in the market: Outstanding blasting pressure bearing capacity, excellent chemical resistance and wear resistance, good surface gloss, low water absorption, good dimensional stability, excellent impact resistance under the condition of-40℃ low temperature, and excellent hydrolysis aging resistance. The core advantages are particularly prominent: under the high temperature of 125℃, the mechanical performance retention rate is more than 80% higher than that of ordinary PA12, and the product has successfully passed the rigorous test of global commercial vehicles. At the same time, Kaisai biology also launched a bio-based low-carbon multi-layer pipeline solution based on EX700, which is suitable for automotive fuel and cooling tube-way scenarios.

Are you confused about selection?

▶Concerned about the insufficient purity of bio-based raw materials, uneven polymerization degree and unstable performance of finished products?
▶Worried about the high procurement cost of bio-based polyamide, the scarcity of mass production cases and imperfect industry certification?

On June 30, 2026, 14:00-15:00, Kaisai bio online technology sharing will start on time! At that time, Xu Weiping, product marketing manager of Kaisai biological strategy marketing department, will be invited to attend, deeply disassembling the performance advantages of bio-based ultra-long carbon chain polyamide material, the case and application details of automobile pipeline industrialization, help enterprises complete material cost reduction, product performance upgrade and low-carbon compliance transformation. We sincerely invite industry engineers, purchasing and R & D leaders to sign up for the meeting free of charge!
