Aluminum hydroxide or ATH is the world's leading flame retardant for plastics and rubber materials, used as a filler and provides non-toxic, smoke-suppressing properties.Aluminum hydroxide is used as a filler for epoxy resins, urethane or polyester resins in which flame retardancy is required.Aluminum hydroxide is the most expensive and suitable inorganic additive flame retardant. It is not only flame retardant, but also prevents smoke, dripping or toxic gases. Therefore, with the increasing use, it is widely used in thermosetting plastics, synthetic rubber, paints and building materials, as well as fillers for artificial marble and PVC wallpaper.Raw materials in aluminum chemical productionRaw materials in glass and glaze manufacturingFlame retardant and smoke-proof fillers in plastics (eg cables, rubber products and carpet backing)Fertilizer raw materialThickeners and tackifiers in paper, solvent and waterborne coatings, UV curable coatings, inks and adhesivesA polishing and cleaning agent, mold cleaning and separating agent. A filler for casting polymer products, such as agate and solid surfaces.Technical IndexAluminum Hydroxide/Alumina Trihydrate/ Aluinum TrihydrateAH-1AH-5AH-10AH-10HAH-12AH-15AH-25AH-90AL(OH)3 %≥99.699.699.699.699.699.699.699.6AL2O3 %≥64.564.564.564.564.564.564.564.5SiO2 %≤0.020.030.030.030.030.030.030.05Fe2O3 %≤0.020.020.030.030.030.030.030.03Na2O %≤0.30.30.30.30.30.30.30.3L.O.I %34.5±0.534.5±0.534.5±0.534.5±0.534.5±0.534.5±0.534.5±0.534.5±0.5Moisture %≤0.30.250.30.30.40.40.30.2Particle Size D50 (μm)1~24~78~129~1210~1414~1823~2775~100Whiteness % ≥9797979594919592Oil Absorption (ml/100g)≤5040332733303035
