Characteristics of Activated Alumina Hydroxide

Produced from premium raw materials through ultra-fine air-flow pulverization and classification, coupled with surface activation of the coupling agent, activated alumina hydroxide fundamentally resolves the shortcomings inherent in traditional alumina hydroxide.

1. As an additive halogen-free smoke suppressant and flame retardant, active aluminum hydroxide features high loading capacity, excellent flame retardancy, and low cost. It significantly improves material arc resistance while enhancing impact strength and flexural strength.

2. Its increased surface area enhances flowability, ensures uniform particle size distribution, and provides excellent stability without generating corrosive gases. It exhibits superior dispersion in resins and resists whitening or warping even at high loading levels. When incorporated into plastics, it remains non-volatile, non-migratory, and retains long-term stability within the material. It demonstrates excellent compatibility with a wide range of substances.

Applications of Activated Alumina

The application scope of activated alumina in manufactured products has expanded significantly, particularly in recent years. Substantial breakthroughs have been achieved in its use as a flame-retardant filler in wires and cables. This application not only enhances electrical performance but also improves flame resistance while minimizing pollution. Additionally, it is applied in insulation materials, flame-retardant hoses, tapes, duct fabrics, and electrical components.
