BASF Red Phosphorus Flame-Retardant PA6: Redefining EV Safety Boundaries Through Material Innovation

1. Technological Breakthrough: Four Core Advantages of Red Phosphorus Flame-Retardant PA6  

1. Leap in Flame Retardancy  

Certified UL 94 V-0 (1.0-1.5 mm thickness), the material self-extinguishes immediately upon flame contact, effectively blocking fire spread caused by battery thermal runaway. Lab data shows a 20% improvement in flame-retardant efficiency compared to conventional organic phosphorus agents, creating a "firewall" for critical components like high-voltage battery modules and busbars.  

2. Mechanical Performance Rivaling Premium Materials  

While retaining PA6’s lightweight properties, the red phosphorus flame-retardant PA6 achieves a tensile modulus of 9,500 MPa, with impact resistance on par with PA66 GF30. It perfectly balances structural strength and flexibility, maintaining stable performance in extreme temperatures (-40°C to 120°C), shattering the myth that "high flame retardancy sacrifices mechanical performance."  

3. Eliminating "Invisible Corrosion" at the Source  

Traditional red phosphorus flame retardants release phosphine (PH3), corroding metal connectors and aging circuits. BASF’s nano-level encapsulation technology reduces phosphorus migration to below 0.05 ppm—a 90% reduction from previous generations—with zero corrosion risk validated by 3,000-hour salt spray tests.  

4. Cost Efficiency and Plug-and-Play Production  

Compared to expensive PA66, red phosphorus flame-retardant PA6 cuts costs by 30%, while its mold shrinkage rate aligns perfectly with traditional PA6 GF30. Automakers can achieve "zero-cost switching" without retrofitting production lines, accelerating safety upgrades.  

2. Applications: Full-Cycle Protection for Battery Systems  

- Battery Module Housing: Flame-retardant layers isolate electrolyte leaks and external heat sources, delaying thermal runaway chain reactions.  

- High-Voltage Junction Boxes & Busbars: Maintains stable electrical insulation under 1,500V high voltage, reducing spark ignition risk by 70%.  

- Sensor Brackets & Connectors: Lightweight design reduces vehicle load, with fatigue resistance extending component lifespan beyond 10 years.  

- Charging Pile Core Modules: Passes GB/T 5169-2020 glow-wire testing (850°C), ensuring charging safety.  

3. BASF Flame-Retardant Expertise: 40 Years of Industry Leadership  

From the first halogen-free flame-retardant PA66 in 1983 to today’s red phosphorus PA6 innovation, BASF has pioneered flame-retardant solutions:  

- Comprehensive Portfolio: Covers 6 major engineering plastics (PA, PBT, PPA, etc.) with 20+ halogenated, halogen-free, and low-emission solutions.  

- Global R&D Network: 237 patents in flame-retardant tech, driven by collaborative efforts between German HQ and Shanghai Innovation Center.  

- Customization: Adjusts glass fiber content (15%-50%) and flame-retardant ratios to meet CTI (Comparative Tracking Index), temperature resistance, and application-specific needs for battery packs and e-drive systems.  

"EV safety shouldn’t be a luxury," states a BASF Asia-Pacific Senior Technical Manager. "We ensure every gram of material embodies safety."  

4. Future Vision: Powering the Electrification Revolution with Material Science  

With the EU New Battery Regulation (mandating carbon footprint declarations by 2027) and China’s upgraded GB 38031-2020 standards, materials combining safety, sustainability, and cost efficiency will dominate the market. BASF’s red phosphorus PA6, certified with 15% lower carbon emissions via ISO 14067, is driving global automakers toward "zero-incident batteries."  

Safety Without Compromise, Innovation Without Limits  

In the EV race, true winners are those who embed safety into their DNA. Starting with red phosphorus PA6, BASF continues to push the boundaries of material science—because every breakthrough redefines what "safety" means.
