Cooperation Content: The client required a lightweight, efficient flame retardant for ABS/PC composites to prevent fire spread. We recommended the silicon-phosphorus composite SiP-800 series, using nanoscale dispersion for improved impact strength and thermal stability. Joint simulations of battery thermal abuse tests optimized additive dosage (1-3%), ensuring compliance with GB 8410.  Results: Flame retardancy reached V-0 level, reducing heat release rate by 40%, and was applied to models from brands like BYD. Post-cooperation, defect rates dropped 10%, annual sales grew 25%, and the client earned national high-tech enterprise certification. This case was featured in industry whitepapers as a benchmark for EV safety materials.
