Flame retardant (Alumiminium hydroxide)

    Flame retardant (Alumiminium hydroxide)

    Aluminum hydroxide is considered the world's most important mineral flame retardant. It is halogen-free and environmentally friendly.

    Properties:

    • Easy to mix in
    • Highly flame retardant (water splitting at 200 °C)
    • Low hardness 3
    • Density 2.4 g/cm3
    • High whiteness (Y color value >94)
    • Coefficient of thermal expansion 15*10-6K-1 (at 20 - 300 °C)

    Technical data:
    Chemical composition: Al(OH)3 99.6 %, Fe2O3 0.01 %, SiO2 0.008 %, Na2O 0.32 %
    Humidity: 0.15 %.
    Grain size: Average grain size 1.0 μm + 325 mesh < 0.1 %.
    Bulk density (kg·m−3): (loose) 0.25, (packed) 0.6
    Oil count: 59 ml/100 g
    Whiteness: 96 %
    pH value (Mixture for pH measurement 30 % flame retardant in water, at room temperature): 9 - 10
    Specific gravity: 2.42
    Refractive index: 1.57
    Hardness (Mohs): 3

    Application:
    As a flame retardant for epoxy resins (casting and laminating resins, gel coats).

    Addition rates:
    25-50 % by weight (25 % in laminates, up to 50 % in topcoats). Preliminary tests for the specific application are recommended.

    Structure of the laminate in the film:
    1) 8 layers of glass fabric tape 220 g/m2 (Art. No. 2001131)
    2) laminating resin epoxy resin L + hardener S + 25 % aluminum hydroxide

    Customer review:
    "The aluminum hydroxide powder was easily and homogeneously mixed into the resin/hardener mixture. Laminating the plies was trouble-free. The resin was given a milky color by the addition and became slightly thixotropic (non-runny, stable)."
