Introduction
Aluminum Hydroxide is a white powder which can be used as flame retardant and filler. While it is used for resin Solid Surface,It has characteristic of white crystalline powder, non-toxic, tasteless, good mobility, low oil absorption, low iron content, particle morphology, particle
size distribution, low impurity content, good stability, high whiteness, uniform particle size and good
dispersibility. While it is used for composite materials,it has characteristic of micro powder,high white powder
without secondary pollution,smoke elimination, filling, antistatic.The initial decomposition
temperature of aluminum hydroxide is about 205 â??. Aluminum hydroxide flame retardant can
release a large amount of water vapor when heated. A large amount of water vapor can store heat
and dilute the concentration of polymer combustible gas. It can also form a non combustible barrier
between the combustion source and the matrix material to achieve the purpose of flame retardant. At the same time, it is also a smoke suppressant, because the gas it releases is water vapor, which
has no corrosion to metals. Usage
Aluminum Hydroxide 14-100um filler powder can be used for MMA and UP solid surface
and artificial marble that used for buildings and home decoration. Aluminum Hydroxide 1-10um flame retardant powder can be used for rubber hose, rubber
plate, carpet, rubber liner, PVC wire and cable material, wire and cable sheath, electrical LDPE
cable material,LSZH wire compound,Silicone rubber,Silastic module,Foam
insulation,Paper-making,PVC industry,Pouring sealant,Shell of
car/phone/plane/computer,toothpaste friction agent, low-voltage insulation devices,glass fiber
reinforced plastic,adhesives, grille, carpet and other industries which required flame retardant.

Super fine Powder Aluminum Hydroxide
Aluminum hydroxide is a kind of filling flame retardant, mainly composed of Al (OH) 3. Aluminum hydroxide micro powder is white powder without secondary pollution. It is an inorganic environment-friendly flame retardant.It is suitable for flame retardant fields such as rubber and plastic products, such as mine conveyor belt, mine air duct coating cloth, hose, rubber plate, carpet, rubber liner, PVC wire and cable material, wire and cable sheath, building materials, damping paste, damping plate , electronics,flame retardant resin.It can be widely used in electrical LDPE cable material,LSZH wire compound,LSZH cable,Silicone rubber,Rubber insulation,Silastic module,Foam insulation,Paper-making,PVC industry,Pouring sealant,Shell of car/phone/plane/computer,conveyor belt, etc. The flame retardant effect of aluminum hydroxide after activated treatment is more better. (the ATH dosage increases after treatment, for example, the normal dosage of untreated 1 micron
size aluminum hydroxide is 30-40%, the dosage can be increased to about 50% after activated treatment).
It can endow products with flame retardant, smoke elimination, filling, antistatic and other
characteristics. The utility model has the advantages of low cost, high performance, good stability, no volatilization, no corrosion to equipment, high decomposition temperature, etc. The initial decomposition temperature of aluminum hydroxide is about 205 . Aluminum
hydroxide flame retardant can release a large amount of water vapor when heated. A large amount of water vapor can store heat and dilute the concentration of polymer combustible gas. It can also form a non combustible barrier between the combustion source and the matrix material to achieve the purpose of flame retardance. At the same time, it is also a smoke suppressant, because the gas it releases is water vapor, which has no corrosion to metals.

Note :
1. AL2O3 content is of the difference of 100% minus firing loss and impurity content.
2. The chemical composition is calculated of the baking at 110í+5íµ for 2 hour .
3. The impurity content is treated in line with the number rule of GB8170.
Physical feature: there are mainly 4 sizes of aluminum hydroxide, 325, 800, 2,000 and 3,000 mesh.
2)Application
Aluminum hydroxide is the most consumable and applicable inorganic additive flame retardant that does not only resist firing, but also prevents from smoke, dropping or toxic gas. So, it is widely used with gradual increase of the usage, at the sectors of hot solidifying and moulding plastic, synthetic rubber, coating and construction materials.
internal plastic with knitted exterior covered with film, with the net weight of 25kg or 40kg
Aluminum hydroxide is the most widely used inorganic flame retardant additive. As a flame retardant, aluminum hydroxide can not only be flame retardant, but also prevent smoking, no dripping and no toxic gas. Therefore, it has been widely used. Scope of application: thermosetting plastics, thermoplastics, synthetic rubber, coatings, building materials and other industries. At the same time, aluminum hydroxide is also the basic raw material of aluminum fluoride necessary for electrolytic aluminum industry, and aluminum hydroxide is also widely used in this industry.

Aluminum Hydroxide for Solid Surface, the appearance of white crystalline powder, non-toxic,
tasteless, good mobility, low oil absorption, low iron content, particle morphology, particle size
distribution. It has low impurity content, good stability, high whiteness, uniform particle size and
good dispersibility.The advanced equipment and technology are used to make the shape of the
product particles closer to the spherical shape. The viscosity and oil absorption rate are maintained
at low levels. Increase the amount of aluminum hydroxide to save resin.
