Based on hydrated alumina chemistry, ATH flame retardants provide halogen-free flame retardancy and smoke suppression by releasing bound water when exposed to elevated temperature. This endothermic reaction helps absorb heat, dilute combustible gases and form a protective alumina residue at the polymer surface. In coatings, rubber and polymer systems, ATH supports reduced flame propagation, lower smoke generation and safer fire-performance formulations while maintaining good dispersion and processing characteristics.
