Aluminum hydroxide

Model: HA-111

Products

Also known as aluminum hydroxide, alumina trihydrate (α-Al2O3 · 3H2O), referred to as ATH, are widely used by the ultrafine synthetic material after the environmental non-halogen flame retardants, flame retardants can be used in conjunction with a variety oforganic produce synergistic Role in enhancing the flame retardant properties andmechanical strength. ATH thermal decomposition of dehydration, heat capacity1967.2J/kg, can effectively inhibit the temperature rise and thermal degradation of polymers. Explain the large amounts of water vapor ATH points to dilute thecombustible gases and inhibit the spread of combustion. ATH-packed crystal structure of double-trigger polymer combustion capture hydroxyl radicals, cut off a chain reaction. ATH in the polymer surface after dehydration temperature dense Al2O3protective film, cut off from the air to prevent fire spread. High-temperature denseAl2O3 protective film can promote carbon polymer, adsorption of solid particles,smoke inhibition of production.

Features

1. Excellent flame retardant and smoke suppression performance - heat dehydrationdecomposition, can effectively inhibit the temperature rise and thermal degradation of polymers by adsorption inhibiting the production of gas for processing moldingtemperature lower than 200 ℃ of the composite material.
2. Good insulation properties - Fluidization purification greatly reduced the ironimpurity ions such as sodium and potassium content.
3. High brightness - do not interfere with composite material staining.

Note: the table model for the conventional product, special specifications can be customized. Physical properties and chemical analysis data for reference only to real product. Indicators in line with the EU RoHS environmental testing indicators.
  Use of guidance
1. alone should be based on the performance requirements of products to choose,size and performance of composite materials is closely related to the smaller size,the better the surface of delicate, the more significant enhancement, but the greaterthe viscosity blends, please carefully adjusted Formula to balance the performance.
2. mixed use different size fill in the appropriate ratios to form in dense polymer systems filled to improve the flame-retardant effect. Reasonable mixed system to avoid settling or floating packing, while reducing the same amount of filling the viscosity of the resin blend, favorable shear dispersion.
3. ultrafine aluminum hydroxide by the specific surface area increased after the easyreunion, poor compatibility with polymers, is difficult to evenly disperse, affecting the physical properties of composite materials. Hydrophobic interface of aluminum hydroxide and polymer compatibility is good, the surface of the substrate resincoating matter sorted groups produced bonding reaction, reducing the viscosity of the blend, to eliminate the interface stress concentration, improve the mechanical properties of composite materials . It is recommended to use hydrophobic products.
4. suggested by experiments to determine the optimal dosage.

Notes
This product should be stored in a cool, dry and ventilated place to prevent ground moisture, avoid high temperature near the heat source. During transportation toprevent water pressure, Handle with care disposal to prevent damaged packaging.Conjunction with other acid, alkaline substances mixed mixed deposit. In more than 80% relative humidity, avoid exposure to air, if necessary, after baking (110 ℃)before use. Should be well sealed container after use of measures proposed after thepackaging opened when the time after use.
