PPSU flame retardant non-dripping
Fenómeno del problema
PPSU itself is highly flame retardant V-0, but thin walls still require verification.
Análisis de la causa
The PPSU main chain contains sulfone groups and aromatic rings, imparting intrinsic flame retardancy.
Solución
Wall thickness <0.8mm still requires UL94 verification; sufficient wall thickness.
Conclusión clave
PPSU flame retardancy is the foundation of its aviation applications.
