Aluminum Hydroxide

to achieve great flame retardancy

ALPHA offers aluminum hydroxide as a primary material for flame retardant fillers. Aluminum Hydroxide, aluminum trihydrate or ATH, is an inorganic compound whose primary use other than aluminum metal production is as flame retardant filler for polymers. Particle size is an important factor for retardant performance and the choice of particle size is made according to the type of application and expected thermal and mechanical properties. ALPHA is ready to produce ATH with different particle size distributions according to the consumer’s request.

Advantages:

  • No toxicity because of manufacturing process
  • No toxic smoke production
  • No toxic waste
  • No destructive effect on the equipment
  • Reducing smoke and dripping

Applications:

  • Insulating parts and enclosures for circuit breakers, contactors, transformers and motors
  • Wire coatings
  • Construction materials
  • Light and fire-resistant materials in the automotive industry
