Aluminum Hydroxid
High whiteness product, low oil absorption rate. ATH has steady performance at room temperature, while in thermal decomposition generating water vapor and aluminum oxide, all this makes the customer’s product have the ability for flame resistance, self-extinguishing, anti-dropping. Besides, it doesn’t produce harmful gas while in thermal decomposition, it’s a suitable inorganic Flame-retardant filler.

The usage in the industrial production
1,Production of alumina products and other inorganic salts: Aluminum hydroxide is often used to produce alumina products, aluminum fluoride, cryolite, aluminum sulfate and other inorganic salts
2,Flame retardant: Aluminum hydroxide has a highly effective flame retardant effect and is often used in polymer materials such as epoxy resin, unsaturated polyester, polyvinyl chloride, etc. to improve the flame retardancy and smoke suppression of the materials
3,Filler material: Aluminum hydroxide can be used as a variety of flame retardants, waterproof fabrics, inks, glassware, paper fillers, etc.
4,Catalyst carrier: High white aluminum hydroxide can be used as a catalyst carrier, especially in catalytic reactions in chemical production
5,Electronic materials: Used to prepare high-purity electronic materials, such as high-temperature superconductors, electronic ceramics, etc.
6,Pharmaceutical industry: Aluminum hydroxide is one of the main ingredients of stomach medicine, used to neutralize gastric acid and treat stomach diseases
Other applications: Aluminum hydroxide is also used in the papermaking industry, ceramic industry, refractory materials, insulating materials and other fields
