Aluminium Hydroxide Al(OH)3 Supplier & Manufacturer

Aluminium Hydroxide

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 ºC. 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.

Hebei Shiguang could manufacture and supply customize products to meet customers' different demands, we are the agent and exporter of Chalco. The company has developed five series aluminum hydroxide, including solid surface fillers, flame retardant fillers, aluminum salts and water purification agents, and other 20 kinds of conventional products.

Advantages of Aluminium Hydroxide

Whiteness and Particle Size Control:
Aluminum hydroxide typically boasts high whiteness, making it suitable for the preparation of high-quality products within the aluminum salt industry. Additionally, particle size can be precisely controlled to meet various processing and application requirements.
High Purity:
High-quality aluminum hydroxide often features a high degree of purity, which is crucial for aluminum salt preparation and other applications. High-purity aluminum hydroxide ensures the quality and stability of the final products.
Chemical Stability:
Aluminum hydroxide generally displays excellent chemical stability, enabling its use as a neutralizing agent for acidic wastewater and gas treatment. It can effectively neutralize substances like sulfuric acid and hydrochloric acid, reducing adverse environmental impacts.
Anti-Caking Properties:
Aluminum hydroxide is typically easy to disperse and resistant to caking, facilitating its handling and processing within the aluminum salt industry.
Hygroscopicity:
Aluminum hydroxide possesses a certain degree of hygroscopicity, making it suitable for wet process production methods. It helps improve the flowability and shape of products.
Filler and Stabilizer:
Aluminum hydroxide can serve as a filler and stabilizer in aluminum salt preparation processes, aiding in achieving uniform reactions and enhancing the quality and yield of products.
Outstanding Fire Resistance:
Aluminum hydroxide is commonly used as a fire retardant due to its ability to release moisture when exposed to flames, reducing the intensity of fires and minimizing thermal radiation.
