Aluminum Hydroxide Micro Powder for Insulators
Aluminum hydroxide is the largest and most widely used inorganic flame retardant additive. Aluminum hydroxide, as a flame retardant, not only can be flame retardant, but also can prevent smoking, produc e no droplets, and produce no toxic gases. Therefore, it has been widely used and its usage is increasing year by year.
Scope of use: industries such as thermosetting plastics, thermoplastic plastics, synthetic rubber, coatings, and building materials. At the same time, aluminum hydroxide is also a necessary basic raw material for aluminum fluoride in the electrolytic aluminum industry, and aluminum hydroxide is also widely used in this industry.
Description
We provide multiple specifications of aluminum hydroxide powder and can customize products according to customer needs. Welcome consulting.
High whiteness aluminum hydroxide micro powder is eco-friendly halogen free flame retardant additive, which is a white loose powder with high whiteness and low bulk density. It is stable at room temperature and undergoes thermal decomposition and dehydration to produce alumina.
This product is different from other flame retardant materials in that it does not produce toxic or corrosive gases during pyrolysis, and absorbs heat and releases water vapor during pyrolysis, making the product flame retardant and self extinguishing. Therefore, adding this product to composite materials such as plastic and rubber not only enhances the flame retardant and smoke eliminating effect of the product, but also enhances its resistance to electric leakage, arc resistance, and wear resistance.

Wide application range
Flame retardant industry
Aluminum hydroxide has moderate hardness, stable physical and chemical properties at room temperature, is non-toxic, and has low production costs. When aluminum hydroxide is heated to around 220C, it begins to absorb heat and decompose, releasing bound water. Due to this endothermic dehydration process, the combustion of the polymer is delayed, resulting in a slower combustion rate.
Wire and cable industry
Adding ultra fine aluminum hydroxide to cable materials can reduce the cost of manufacturing cables and improve their flame retardant properties. Knowing the appropriate, feasible, and easy to operate analysis method for key physical indicators of ultra fine aluminum hydroxide will play a crucial role in the development of new raw materials.
BMC, SMC industry
BMC/SMC specific aluminum hydroxide can not only be flame retardant, but also remove droplets and toxic components caused by combustion of organic matter. It has the functions of flame retardancy, smoke suppression, and anti droplet. More suitable for use in fields such as thermosetting plastics, coatings, fiberglass, resins, electronics, and glass products.
Sealing adhesive industry
Modified aluminum hydroxide has brought new possibilities to the field of electronic sealing adhesive. Its excellent thermal conductivity endows the sealing adhesive with stronger heat dissipation function. Modified aluminum hydroxide also exhibits excellent heat resistance and corrosion resistance, allowing the sealing adhesive to maintain its function and performance in extreme environments.
Applications in the electronics industry
Aluminum hydroxide can be used as a purifying agent for semiconductor materials, as a raw material for the preparation of pure crystalline silicon, to help manufacture high-quality semiconductor materials. Aluminum hydroxide can also be used as a filler in microelectronic processing, reducing factors such as pressure and thermal diffusion in chips, and filling small cracks to improve chip performance.
Paper Industry
Aluminum hydroxide has strong adsorption properties and can be used to prepare coatings and fillers for producing high-quality paper. In addition, aluminum hydroxide can also be used to adjust the acidity and alkalinity of paper to improve its quality.
Artificial marble
Aluminum hydroxide is widely used in the artificial marble industry by filling materials with aluminum hydroxide and unsaturated polyester resin. So, it is possible to create a texture of marble, and the effect is very good.
Toothpaste materials
Aluminum hydroxide is also used in toothpaste production enterprises. By using aluminum hydroxide, attachments on the surface of teeth can be removed, and aluminum hydroxide is a non-toxic and harmless substance that does not cause any damage to the gums.
