Char Former

Char‑forming additives are used to boost the effectiveness of many flame retardant systems by promoting the formation of an insulating, carbonized layer when exposed to fire. This protective char shields the underlying polymer from heat and oxygen, slows volatilization of combustible gases, and helps limit flame spread, smoke generation, and overall fire growth, supporting compliance with more demanding flammability standards.
