Alumina Trihydrate (ATH)


Alumina Trihydrate, commonly known as ATH, is a versatile and widely used compound in various industries. With its chemical formula Al(OH)3, ATH is a white, odorless powder that exhibits excellent flame-retardant properties. It is extensively employed as a flame retardant and smoke suppressant in plastics, coatings, and construction materials.

ATH acts as a heat sink by releasing water vapor when exposed to high temperatures, effectively reducing the risk of fire and limiting smoke generation. Additionally, this mineral filler is renowned for its non-toxic nature and compatibility with different polymers, making it a preferred choice for enhancing fire safety in numerous applications.

Primary Applications:

  • Flame retardant
  • Smoke suppressant
  • Filler for solid surface materials
  • Adhesives and sealants
  • Cable compounds
  • Paints and coatings
  • Thermoset resins
  • Rubber and polymer compounds
  • Pharmaceuticals and cosmetics
  • Glass manufacturing
