Application of aluminum hydroxide CAS number: 21645-51-2
Aluminum hydroxide is white powder, the main component is al (OH) 3, which has the characteristics of good fluidity and high whiteness.
1. Aluminum hydroxide can prevent smoking, produce no drops and no toxic gas. It is easy to decompose in strong alkali and strong acid solution, heat, decompose and dehydrate into alumina. It is suitable for molding materials, rubber plastic foaming materials, thermosetting plastics, thermoplastics, synthetic rubber, coatings, FRP, resin, electronics, ceramics, glass products, etc.
2. Active aluminum hydroxide adopts domestic advanced production technology (surface treatment with silane or stearic acid and other coupling agents) and is activated and modified by a variety of additives and coupling agents. It has high fineness, narrow particle size distribution, good flame retardant effect, high whiteness and low bulk density, and can be added more. (there are two kinds of silane: domestic and imported, and the imported silane is mainly the series silane products of Dow Corning company of the United States)
3. Aluminum hydroxide can be used as a flame retardant additive for various aluminide raw materials, plastics, rubber and other flammable materials, artificial marble filler, papermaking, surface pigment, coating, toothpaste substrate, fluoride, artificial agate, glass mosaic, building material quick setting filler, SMC \ BMC molding material filling Rubber and plastic materials are used as fillers for copper sheet paper surface coating and flame retardant paper. The surface of copper paper is smooth, shiny and has strong absorption of ink.
4. Active aluminum hydroxide can improve the combination and processability of aluminum hydroxide and resin, making it both flame retardant and filling properties. Therefore, adding this product to advanced composites such as plastics and rubber not only makes the product have flame retardant and smoke elimination effect, but also enhances the anti leakage, arc resistance and wear resistance. It can be widely used in electrical LDPE cable material, rubber, wire and cable insulation layer, sheath layer, BMC molding material, rubber and plastic material, thermal insulation material, conveyor belt, copper clad laminate, substrate, etc.

Inorganic flame retardant filler - aluminum hydroxide product introduction:
Aluminum hydroxide is white powder with relative density of 2.42 and Mohs hardness of 3.0. It has the characteristics of non-toxic, tasteless, good dispersion, high whiteness and low iron content. Aluminum hydroxide is widely used in the following aspects: artificial marble filler; Flame retardant fillers for vinyl chloride paste, epoxy resin, unsaturated polyester resin and other plastic products; Catalyst and catalyst support; Toothpaste filler; Paper making filler and coating agent; High purity glass special fillers, high purity aluminum salt fillers and fiber post-processing additives for integrated circuits and optics; Electronic and electrical potting adhesive, epoxy resin castable, plastic sealing material, LED packaging material, electrical switch, wire and cable material, foaming material, high-performance adhesive, coating, fireproof board, artificial stone, artificial leather, polyurethane, polyamide, polyolefin, unsaturated polyester resin, synthetic rubber and other functional polymer products. 

Aluminum hydroxide, also known as alumina trihydrate, or ath for short, is widely used as an environment-friendly halogen-free flame retardant for synthetic materials after ultra refinement. It can cooperate with various organic flame retardants to produce synergistic effect and improve the flame retardant performance and physical and mechanical strength of materials. ATH is dehydrated and decomposed by heating, and its heat absorption capacity reaches 1967.2j/kg, which can effectively inhibit the temperature rise and thermal degradation of polymers. A large amount of water vapor released by ath decomposition can dilute combustible gas and inhibit combustion spread. The close packed double-layer crystal structure of aluminum hydroxide can capture the hydroxyl radical causing polymer combustion and cut off the chain reaction. After ath dehydration, a high temperature resistant dense Al2O3 protective film is formed on the polymer surface to isolate air and prevent flame spread. High temperature resistant dense Al2O3 protective film can also promote polymer carbonization, adsorb solid particles and inhibit the generation of dense smoke.

Aluminum hydroxide is one of the largest inorganic flame retardants in the world. It has three functions: flame retardant, smoke elimination and filling. It has no secondary pollution during combustion, does not produce toxic and corrosive gases during pyrolysis, absorbs heat and releases water vapor, and has flame retardant and self extinguishing properties. It not only has good dispersion in polyolefin, but also is easy to produce flame retardant synergistic effect with other additives. In addition, due to the existence of crystalline water, it can also endow polymer products with antistatic function, and improve the strength and toughness of polymer.

Product features:
1. Aluminum hydroxide is an excellent flame retardant and smoke suppression performance - it is decomposed by dehydration when heated. After dehydration, A1203 protective film is formed on the surface of combustibles to isolate oxygen, reduce the concentration of combustible gas and oxygen, effectively inhibit the temperature rise and thermal degradation of polymers, inhibit the generation of flue gas through adsorption, make it carbonized and not easy to produce combustible volatiles, and prevent combustion, It is suitable for processing composite materials with molding temperature lower than 200 ºC.
2. Aluminum hydroxide has good insulation performance - fluidization purification process greatly reduces the content of iron, sodium, potassium and other impurity ions.
3. High whiteness aluminum hydroxide - does not interfere with the dyeing of composite products.
4. Aluminum hydroxide content of low iron - less than double zero five (i.e. 0.005%).

Application reference of technical parameters of conventional products:
The models listed in the above table are the basic products of the company, and special specifications can be customized according to needs. Products with D50 of 5, 8, 10, 14, 20, 25, 90 microns are normally prepared. In addition, according to the user's requirements, the product can be surface treated to reduce the processing viscosity, enhance the affinity, improve the flame retardancy and physical properties of the product, and the environmental protection detection index meets the EU ROHS index.

Guidance for the use of aluminum hydroxide:
1. For separate use, it should be selected according to the performance requirements of the products. The particle size is closely related to the properties of the composite materials. The smaller the particle size, the better the surface fineness and the more significant the enhancement effect, but the greater the viscosity during blending. Please carefully adjust the formula to balance various properties.
2. Mixed filling with different particle sizes can form dense filling in the polymer system at an appropriate proportion to improve the flame retardant effect. A reasonable composite system can avoid the settlement or floating of filler, reduce the viscosity of resin blends with the same amount of filler, and is conducive to shear dispersion.
3. After ultra-fine aluminum hydroxide, due to the increase of specific surface area, it is easy to agglomerate, poor compatibility with polymer and difficult to disperse evenly, which affects the processability of the composite. Hydrophobic aluminum hydroxide has good interfacial compatibility with polymers. The surface coating can bond with the base resin groups, reduce the viscosity of the blends, eliminate interfacial stress concentration and improve the mechanical properties of the composites.
