The article reviews the grades and application cases of automotive flame-retardant materials like ABS, PC, and PP, covering flame retardant selection and UL94 V-0 data, to help quickly match flame-retardant solutions for automotive components.
The white frost on flame-retardant PP originates from flame retardant migration and precipitation. The article offers three solutions: compatibilizer coating, low-temperature/low-shear processing, and post-treatment annealing, achieving Grade 0 precipitation in tests, helping flame-retardant PP maintain a lasting bright surface while achieving UL94 V-0.
Piperazine pyrophosphate flame retardant application dismantles the 4 major challenges behind the advantages of halogen-free flame retardants: water resistance/leaching, processing corrosion, a narrow synergy window, and difficulty achieving V-0 in thick sections. It provides practical test solutions for nylon and PE flame retardancy, helping you stably achieve UL94 V-0.
