CAS 21645-51-2
Structure {[CurrentData.Name]}
Description Aluminium trihydroxide (ATH) is a halogen free flame retardant filler. When heated above temperatures of approximately 200°C, an endothermic reaction will take place, liberating 3 molecules of crystal water and thereby removing energy from the combustion zone.
The loss of 34.6 % of its weight as water vapour also dilutes combustible gases. Furthermore, no toxic smoke or decomposition products are formed during this reaction, making ATH an ideal product to comply with regulations.
