Aluminium Trihydrate :-
(AI2O33H2O) is the most widely used flame retardant in the world due to its versatility and low cost. Available in different particle sizes, it can be used in a wide range of polymers at processing temperatures below 220C. ATH is non-toxic, halogen-free, chemically inert, and has low abrasiveness. Additional benefits are an arc and track resistance in plastics exposed to electrical arcing, acid resistance, and smoke suppression. At about 220C, ATH begins to decompose endothermically releasing approximately 35% of its weight as water vapour.
