Aluminum Hydroxide (Al(OH)₃) for flame retardant has follow features：

Superior flame retardant performance

Aluminum hydroxide can undergoes decomposition reactions at high temperatures, releasing a large amount of water vapor and absorbs a significant amount of heat, effectively lowering the temperature around the material and thereby inhibiting the progress of combustion reactions

Filling and reinforcing effect

Aluminum hydroxide can increase the hardness of the material and make it more wear-resistant. Enhance the strength of the material to enable it to withstand greater external forces; At the same time, it can also enhance the dimensional stability of the material, reduce deformation caused by factors such as temperature changes and external forces, and ensure the accuracy and reliability of the product during use

Excellent electrical insulation

When manufacturing electrical equipment such as switch cabinets and insulators, these composite materials can effectively prevent current leakage, ensuring the safe and stable operation of the equipment and reducing the risk of safety accidents caused by leakage.

Environmentally friendly and non-toxic

Aluminum hydroxide is an environmentally friendly flame retardant. It is non-toxic and harmless in itself and will not cause pollution to the environment during production and use

Application Field

Aluminum hydroxide as a flame retardant add in SMC(Sheet Molding Compounds) and BMC (Bulk Molding Compounds) materials to manufacture building materials such as fireproof boards, decorative boards and ventilation ducts

Electronic and electrical appliance casings: Such as the casings of televisions, computers, mobile phones and other devices, which can not only be flame-retardant but also reduce the release of toxic gases during combustion, ensuring safe use.

Coatings and Coatings:Steel structure fireproof coating: Applied to the surface of steel structures, when exposed to fire, aluminum hydroxide decomposes and absorbs heat, delaying the temperature rise of steel and prolonging the fire resistance time of steel structures.

Aerospace materials: Used in aircraft interiors and composite materials to meet strict flame retardant and environmental protection requirements.

Production Process And Quality Control

We adopt advanced production techniques. From the selection and procurement of raw materials, to the precise control during the production process, and then to the strict inspection of finished products, every link adheres to strict quality standards. During the production process, by precisely controlling the reaction conditions and optimizing the process flow, the stability and consistency of key indicators such as the purity and particle size distribution of the aluminum hydroxide products are ensured. At the same time, we are equipped with a professional quality inspection team and advanced inspection equipment to conduct comprehensive inspections on each batch of products, including chemical composition analysis, particle size inspection, whiteness inspection, oil absorption value inspection, etc. Only products that fully meet the quality standards can enter the market, providing customers with high-quality and stable performance aluminum hydroxide products.
