AluminIum trihydrates (ATH) are obtained by digestion of bauxite throughout the Bayer process.
Alumina trihydrate starts to remove constitution water above 180 ° C. Water removal cools the surface and eliminates entry of oxygen, which confers flame retardant properties and smoke suppressant. Accordingly it is a necessary raw material for products like rubber, polyurethane, polyester, silicone, thermoplastic, cables, etc. with fire retardant properties.
