1、 Application of Chuangyongjia PA6 material in new energy vehicles
Chuangyongjia modified PA6 material has excellent toughness, good formability, and high cost-effectiveness. After flame retardant and glass fiber reinforcement modification, its mechanical and safety properties are greatly improved. It is mainly used in new energy vehicle battery systems and core structural components of the vehicle body.
The new energy vehicle battery box, partition, high-voltage cover plate, control unit housing and other components have strict requirements for material flame retardancy, strength, impact resistance, and insulation. The original PA6 flame retardant grade is only UL94 V-2, which cannot meet the safety standards for new energy vehicles. In response to this, Chuangyongjia has independently developed halogen-free flame-retardant glass fiber reinforced PA6 material, abandoning the environmentally poor halogen flame retardant system and adopting a multi axis glass fiber layout process to achieve UL94 V-0 high flame retardant level, significantly improving material stiffness, strength, and energy absorption capacity. It can accurately match the load requirements of high-voltage battery components, effectively resist impact, vibration, and high temperature erosion during driving, and comprehensively ensure the safe operation of power battery systems. At the same time, the company has launched continuous fiber-reinforced PA6 composite materials, which can be used to make new energy vehicle battery brackets with stronger structural stability.
In the field of vehicle structural components, the performance of Chuangyongjia long glass fiber reinforced PA6 material is comparable to that of metal materials. The glass fiber uniformly penetrates the substrate, effectively improving the material's creep resistance, high and low temperature resistance, and impact resistance. It can be integrated into complex automotive structural components. This material has been successfully applied to the dashboard crossbeam of automobiles, which not only meets the high-strength requirements of component load-bearing, collision buffering, and supporting airbags, but also has excellent fatigue resistance and NVH performance, which can eliminate driving resonance and abnormal noise. The all plastic molding process not only improves production efficiency, but also effectively achieves lightweighting of the vehicle body, and has been mass-produced with multiple models.
2、 Application of Chuangyongjia PA66 material in new energy vehicles
Compared to PA6, Chuangyongjia modified PA66 material has a higher melting point, lower water absorption rate, better dimensional stability and heat and aging resistance, and faster crystallization speed and high molding efficiency. It is the preferred material for automotive high-temperature working conditions, high precision, and high-pressure components, widely suitable for core components of fuel vehicles and new energy vehicles, and helps with vehicle lightweighting, noise reduction, and consumption reduction.
In response to the high temperature condition of 200 ℃ in modern engine compartments, Chuangyongjia High Heat Resistant Modified PA66 can replace traditional materials to make intake manifolds. It is resistant to high temperatures, not easily deformed or aged, and has high molding accuracy, effectively optimizing engine efficiency and reducing energy consumption. Fiberglass reinforced PA66, with its excellent damping and vibration reduction properties, can replace steel and aluminum metal materials in engine and drive motor bracket components. While meeting the requirements of load-bearing and deformation resistance, it effectively attenuates equipment vibration noise and optimizes the overall NVH performance of the vehicle. This material can withstand a baking paint temperature of 160-180 ℃ and can be integrated into the interior of a car's white body. It efficiently absorbs impact energy during collisions, protecting the safety of drivers, passengers, and power batteries. It achieves a weight reduction of more than 30% for the car body and significantly improves vehicle handling and new energy vehicle range.
In the field of new energy high-voltage electrical, Chuangyongjia organic phosphorus halogen-free flame retardant reinforced PA66 material is suitable for core high-voltage components such as car chargers, DC/DC controllers, high-voltage junction boxes, and high-voltage connectors, with UL94 V-0 flame retardant performance, excellent insulation and mechanical properties. At the same time, the company optimizes the PA66/PA6 alloy modification process, scientifically balances the material's heat resistance, flame retardancy, toughness, and cost, effectively avoids the risk of raw material price fluctuations, and provides a cost-effective solution for automotive high-voltage components.
In addition, Chuangyongjia short cut carbon fiber reinforced PA66 composite material can be used to make lightweight battery cases for new energy vehicles. Compared with traditional metal cases, it reduces weight by 84%, reduces stress on the case by 30% to 50% under complex working conditions, reduces deformation and displacement of the case, and greatly improves structural durability. In response to the problem of low-temperature brittleness in ultra long rolled strips for automobiles, the company has developed a cold resistant and toughened PA66 material through twin-screw blending modification technology, which is suitable for low-temperature working conditions in vehicles and outdoors. In response to the pain points of hydrolysis and explosion of automotive cooling water pipes, modified PA66 material has added hydrolysis resistance and toughening properties, resulting in a cooling water pipe with a burst strength of over 2.6MPa and a production cost reduction of 40%. It can perfectly replace expensive traditional long-chain PA water pipes.
3、 Product advantages and industry outlook
With the continuous promotion of new energy and lightweighting in automobiles, the market demand for automotive nylon materials is steadily increasing. Chuangyongjia modified PA6 and PA66 materials have core advantages such as high temperature resistance, high toughness and rigidity, high dimensional accuracy, good thermal stability, weather resistance and corrosion resistance, easy molding, and low warpage, which can fully meet the production needs of automotive enterprises for high precision, high safety, and low cost.
In the future, Chuangyongjia will continue to deeply cultivate the field of automotive polymer materials, relying on mature research and development and production systems, continuously iterating and optimizing PA6 and PA66 modified products, focusing on core application scenarios such as automotive batteries, electronic control, power, and body structure, and providing customized and high-performance material solutions to help the automotive industry achieve lightweight, low-carbon, and high-end upgrades.
