Guangdong Chuangyongjia New Materials Co., Ltd
Chuangyongjia New Energy Vehicle Battery System High Temperature Modified Plasti
With the rapid iteration of the new energy vehicle industry, 800V high-voltage fast charging, CTP non module, and CTC chassis integration have become the mainstream technology routes in the industry. The power battery is subjected to multiple extreme working conditions such as continuous high temperature, instantaneous thousand degree thermal runaway, high voltage insulation, electrolyte corrosion, and long-term mechanical creep for a long time. Traditional steel and aluminum shells have a heavy weight and complicated assembly processes. Ordinary general-purpose plastics have poor heat resistance, flame retardancy, and insulation performance, making it difficult to meet the triple core requirements of vehicle lightweighting, safety compliance, and cost reduction in mass production at the same time.
In response to the common material selection pain points in the industry, Guangdong Chuangyongjia New Materials relies on nearly 30 years of polymer modification technology accumulation to create a complete solution for layered gradient high-temperature modified plastics, covering all components of the battery system, combined with four self-developed bottom layer modification technologies, balancing safety performance, lightweight benefits, and large-scale production costs, providing one-stop customized material supporting services for automotive companies, battery factories, and energy storage enterprises.

2、 The five fatal working conditions of power batteries highlight the shortcomings of traditional materials
From installation, fast charging and discharging to long-term outdoor service, power batteries face five major irreversible failure risks throughout the process, which are also the core assessment indicators for battery material selection:
1. Long term steady-state high-temperature aging: The conventional working range of the battery cell is 60-95 ℃, and the local temperature of the busbar and BMS can reach 150 ℃. Under long-term high temperature, the flame retardant precipitates, the material becomes brittle, the size drifts, and the insulation and structural strength weaken year by year in ordinary plastics;
2. Instantaneous burning of battery cells due to thermal runaway: Overcharging or collision short circuit of battery cells can cause thermal runaway, and the instantaneous temperature can exceed 1000 ℃. Ordinary plastic melts and drips, which can easily ignite surrounding battery cells and cause a chain fire in the entire vehicle;
3.800V high voltage insulation failure: The high voltage platform has strict requirements for material water absorption and leakage tracing index. Ordinary plastics may experience creepage and arc breakdown after absorbing moisture, posing a threat to the electrical safety of the entire vehicle;
4. Chemical corrosion of electrolyte: Carbonate electrolyte has strong corrosiveness, and leakage can cause ordinary plastics to swell and crack, directly damaging the insulation structure;
5. Long term load creep deformation: vehicle bumps and vibrations, continuous expansion and compression of battery cells, slow deformation of ordinary plastics, resulting in problems such as loose fasteners, seal failure, and shell warping.
The metal shell is heat-resistant and stable, but it is heavy and requires multiple welding/assembly processes, resulting in high overall material and labor costs; A single universal plastic cannot simultaneously meet multiple indicators of heat resistance, flame retardancy, insulation, and chemical resistance. The gradient modification system of Chuangyongjia abandons one size fits all material selection and matches corresponding substrates according to risk levels, achieving the optimal cost-effectiveness of all components.
3、 Six gradient modified substrates for precise matching of all battery system components
Chuangyongjia has a complete layout of six substrate systems, including PC/ABS, modified PP, ceramicized PA66, low water absorption MPPO, weather resistant PBT, and high-temperature PPS, covering all components of the battery lower shell, upper cover, high-voltage junction box, busbar, connector, and thermal insulation firewall. The company's product photos of particles and injection molded parts can be directly matched with promotional illustrations:
1. Economical long glass fiber PC/ABS | battery lower shell, module fixed bracket directional long glass fiber reinforced formula, heat deformation temperature ≥ 110 ℃, stable to UL94 V-0 halogen-free flame retardant standard, resistant to high temperature creep and driving impact vibration. The material has excellent melt flow and is suitable for injection molding of large-sized integrated shells. Compared with steel chassis, it reduces weight by more than 40% and has a high yield rate in mass production. It is the preferred cost-effective option for chassis structural components.
2. Ceramic modified PA66 | The main upper cover of the battery pack and the battery cell isolation bulkhead are mainstream thermal safety materials for current mass production models. The core advantage is the high-temperature ceramic protective layer, which can directly replace mica, aerogel and other external thermal insulation materials without melting and dripping when burned by an open flame at 1300 ℃, simplifying the internal structure of the battery pack. HDT can reach up to 200-220 ℃, replacing aluminum alloy covers to reduce weight by 50%, overall assembly and auxiliary material costs by 30%, and is suitable for the vast majority of passenger car CTP projects.
3. Low water absorbing fiberglass MPPO | 800V high-voltage BMS shell and high-voltage junction box have a saturated water absorption rate of less than 0.1%, and injection molding production does not require pre baking, greatly reducing production hours and energy consumption; CTI leakage trace index ≥ 600V, dielectric strength>20kV/mm, long-term insulation performance in the engine room environment of 80-110 ℃ without degradation, completely solving the pain point of high voltage shell moisture leakage industry, suitable for high-end 800V fast charging platform.
4. Weather resistant PBT | BDU shell and high-voltage wire harness connector have an arc resistance time of over 180 seconds, UV and high temperature resistance, and color fading. They support black and orange integrated color matching molding, eliminating the need for secondary spraying and reducing VOC emissions. The injection molding process has a wide window and low scrap rate, ensuring long-term electrical stability of high and low voltage connection parts.
5.Fiberglass flame retardant modified PP, lightweight module partition, and economical battery cover have the lowest density and the best raw material cost among the six systems. The 20% -40% long fiberglass reinforced version has a thermal deformation temperature of 125-145 ℃; Upgraded ceramic PP can withstand 1200 ℃ fire for 10 minutes without penetration, balancing lightweight and basic thermal protection, suitable for entry-level CTP module cost reduction needs.
6.High end special PPS | thermal runaway firewall, high-voltage busbar insulation base complete solution with the highest safety level substrate, UL94 V-0 flame retardant, without the need for additional large amounts of flame retardants; Continuous use temperature above 200 ℃, hot deformation temperature exceeding 250 ℃, rigidity comparable to aluminum alloy. The 3mm thin plate was burned with a flame at 1000 ℃, and the temperature on the back remained stable below 150 ℃, fully meeting the GB38031 two-hour thermal runaway national standard. It is a thermal safety backing material for CTC integrated high-end vehicle models.
4、 Four self-developed core modification technologies to solve material congenital defects at the molecular level
Create the performance of all battery specific modified materials for Yongjia, relying on four independently developed modified underlying technologies to achieve stable and large-scale production of laboratory formulas:
1. Three element high-temperature composite antioxidant system: a combination of main and auxiliary antioxidants and carbon free radical scavengers. After rigorous aging testing at 95 ℃ for 1000 hours, the material's tensile strength retention rate is ≥ 85%, and it does not yellow or crack after long-term use;
2. Microcapsule halogen-free phosphorus nitrogen flame retardant technology: The flame retardant component is encapsulated in microcapsules, which do not migrate or precipitate at high temperatures, do not corrode metal conductive contacts, and meet low VOC environmental regulations for car interiors;
3. High temperature ceramic modification technology: compounding silicon-based inorganic ceramic fillers, generating a continuous and dense ceramic insulation layer in situ at temperatures above 600 ℃, blocking heat and flame conduction, and suppressing thermal runaway diffusion from the source;
4. Interface grafting electrolyte resistance modification: Molecular level grafting protective structure, with a swelling rate of less than 1.2% after continuous immersion in 85 ℃ electrolyte for 720 hours, effectively resisting chemical corrosion and avoiding stress cracking of components.
5、 The four major landing values of the entire solution are adapted to the trend of next-generation battery technology
1. Lightweight directly improves the range of the vehicle
The entire range of modified plastics replaces metal structural components to achieve a weight reduction of 20% -60%: PPS reduces weight by 20% -30%, ceramic PA reduces weight by 30% -40%, and MPPO reduces weight by up to 60%. The weight under the spring of the entire vehicle has decreased, reducing driving energy consumption, which can directly improve the range performance by 5% -10%, while optimizing the quality of vehicle acceleration and braking control.
2. Full chain material and production cost reduction
The unit price of modified raw materials is lower than that of aluminum alloy, and integrated injection molding can reduce the number of components; Ceramic PA and PPS eliminate mica and aerogel lining, PBT does not need secondary spraying, and comprehensive material+assembly cost decreases by about 30%. PP and PC/ABS non baking formulas shorten the injection molding cycle and improve the daily production capacity of automated production lines.
3. Compatible with CTP and CTC integrated advanced manufacturing processes
The material is compatible with various mainstream processes such as hot runner injection molding, LFT-D long fiber molding, and continuous fiberglass composite molding. It can be integrated into a 1-2 meter large-sized battery cover and an integrated chassis shell, perfectly adapting to the next generation battery architecture without modules and chassis integration, giving greater freedom to the overall vehicle structure design.
4. Layered all-round security redundancy protection
Build a gradient security protection network from the bottom economic PP structural components, middle ceramic PA thermal protection components, and top PPS extreme firewall. Ceramic materials prevent the uncontrolled spread of heat, MPPO and PPS ensure the stability of 800V high-voltage insulation, while taking into account the multiple properties of electrolyte resistance, aging resistance and creep resistance, and comprehensively avoiding various potential safety hazards of the battery system.
6、 Material Innovation
The safety, lightweighting, and integration of new energy vehicles are irreversible industry trends. Traditional metal shells are no longer able to balance the contradiction between performance, weight, and cost. High performance modified engineering plastics have become the core route for upgrading power battery materials.
Guangdong Chuangyongjia New Materials has been deeply involved in the field of battery modified plastics for many years. It does not rely on a single material to "sacrifice performance for low price", but instead customizes a layered solution based on the temperature, voltage, stress, and fire resistance requirements of different components of the battery system. The entire set of materials meets the national safety standards for power batteries, while also taking into account the process adaptability and cost control needs of leading car companies for large-scale production.
In the future of the 800V high-voltage fast charging and CTC chassis integration industry, Chuangyongjia will continue to deepen the research and development of ceramic, high insulation, and chemical resistant special materials, and provide stable, compliant, and cost-effective high-temperature modified plastic overall solutions for new energy vehicle and energy storage enterprises.
