Ultra-fine aluminum hydroxide (ultra-fine ATH), an ultra-fine grain of Al(OH) 3 usually having a particle size of 1-2 microns or less in size. It has a high specific surface area because of its small particle size, which is good for dispersion during polymer production, flame-retardancy and smoke-suppressant characteristics. It has a purity above 99% purity, with a high degree of whiteness (≥95%), and very few impurities (such as SiO₂, Fe₂O₃, Na₂O), and is therefore an ideal choice as a thermal resistant, non-abrasive and non-corrosive and wear-resistant material. Because of these qualities, it fits very well in environmentally friendly flame retardants in plastics, electronics, cables and rubber products, especially with regards to environmental safety and fire retarding purposes.

Ultra-fine ATH is multi-purpose thermoplastics, thermosets, and adhesive filler as well as a coatings, dispersant, film-forming agent, and thickener in industry and pharmaceutical applications, besides fire-retarding. Its high surface area can make it a valuable catalyst carrier and ceramic products such as high-purity alumina and semiconductor components and bio-implants. It has a tendency to agglomerate due to its small particles, but once this is treated on the surface through stearic acid or silane, and complicated techniques of chemical manufacturing, a greater compatibility and dispersible manner will be able to occur. Due to the rising demand for halogen-free, eco-friendly fire retardants and due to stricter fire safety standards, the consumption of ultra-fine ATH is also rising at an alarming rate globally.

COVID-19 IMPACT

Pandemic disrupted supply chains and industrial demand which severely affected the market

The global COVID-19 pandemic has been unprecedented and staggering, with the market experiencing lower-than-anticipated demand across all regions compared to pre-pandemic levels.
