Description
64% Aluminium Hydroxide (ATH, Al(OH)₃)
64% Aluminium Hydroxide, also known as Alumina Trihydrate (ATH), chemical formula Al(OH)₃, CAS No.21645-51-2, white soft mineral powder with 64% minimum alumina equivalent content. It is a non-toxic, halogen-free flame retardant that decomposes endothermically under heat to absorb heat, release water vapor and suppress smoke & toxic fumes.
Core Application Industries
- Water-based Coatings & Latex Paint Halogen-free flame retardant filler for interior fireproof paint, wall coatings, improves paint flatness, whiteness and fire resistance without affecting color.
- PVC Plastic & Cable Masterbatch Main low-smoke flame retardant for wire & cable materials, plastic profiles, injection molding parts, reduces fire hazard of plastic products.
- Artificial Stone & Solid Surface Functional filler for quartz stone, acrylic solid surface, boosts hardness, anti-flaming performance and uniform texture.
- Ceramic & Glaze Raw Material Adjust glaze melting point, enhance glaze whiteness and thermal stability, reduce firing defects for daily ceramics and tiles.
- Rubber & Adhesive Flame retardant and reinforcing filler for fire-resistant rubber, water-based glue.
Our 64% aluminium hydroxide features controllable mesh fineness, low oil absorption, good dispersion in resin, water slurry and glaze slip, consistent alumina content batch by batch, stable flame retardant effect for mass production.
