The flame-retardant mechanism of aluminum hydroxide flame retardants involves extinguishing flames.

As public awareness of safety and health continues to rise, aluminum hydroxide flame retardants have gradually become an indispensable part of our daily lives. Countries worldwide still prioritize the development of flame retardants as a key task, achieving notable progress. So, how exactly does aluminum hydroxide flame retardant extinguish flames and provide fire resistance?

Aluminum hydroxide flame retardants participate in polymerization reactions as monomers. This inherently incorporates flame-retardant components into the polymer itself, offering the advantage of minimal impact on the material's performance properties. Their enduring flame-retardant effect is achieved through multiple mechanisms, including heat absorption, surface coverage, chain reaction inhibition, and suffocation by non-combustible gases. Most flame retardants achieve their purpose through the synergistic action of several mechanisms.

Aluminum hydroxide flame retardants are functional additives that impart flame resistance to combustible polymers. Primarily designed for polymeric materials, they exist in multiple types. Based on application methods, they are categorized as additive aluminum hydroxide flame retardants and reactive aluminum hydroxide flame retardants.

Additive aluminum hydroxide flame retardants are incorporated into polymers through mechanical mixing to impart flame retardancy. Currently, the main types of additive aluminum hydroxide flame retardants are organic aluminum hydroxide flame retardants and inorganic aluminum hydroxide flame retardants. Aluminum hydroxide flame retardants (organic chlorides and organic bromides) and non-halogenated types absorb heat generated during combustion, acting to cool and slow the burning rate.
