Flame‑Retardant Modified PA6

Unmodified PA6 has a limiting oxygen index (LOI) of merely 20%‑22%. It is combustible and generates burning drips, hence flame‑retardant modification is required. Halogen‑free flame retardancy represents the mainstream technical route, covering phosphorus‑based, nitrogen‑based, silicon‑based and phosphorus‑nitrogen synergistic flame retardants. Phosphorus‑based flame retardants promote dehydration and carbonization of polymer matrix during combustion, forming dense char layers to isolate oxygen and heat. Nitrogen‑based flame retardants such as melamine cyanurate (MCA) decompose under heat and release non‑combustible gases, which dilute oxygen concentration and absorb heat for cooling. Compound flame‑retardant formulations deliver superior flame‑retardant performance via multi‑element synergistic effects.

Main Applications

Widely applied to fields with strict fire‑safety requirements, including electronic & electrical products, connectors, circuit breakers and new‑energy components.
