Key Quality Indicators to Consider When Selecting Flame-Retardant Aluminum Hydroxide

Flame-retardant aluminum hydroxide offers advantages such as non-toxicity, excellent stability, and the absence of toxic gases at high temperatures. It reduces smoke and soot emissions during plastic combustion and exhibits a low dehydration endothermic temperature.

Flame-retardant aluminum hydroxide offers advantages such as non-toxicity, excellent stability, and the absence of toxic gases at high temperatures. It reduces smoke and soot emissions during plastic combustion and exhibits a low dehydration endothermic temperature. Flame-retardant polyolefins containing 60% aluminum hydroxide can be used as construction materials and interior decoration materials for automobiles and ships.

The flame-retardant aluminum hydroxide primarily used as a flame retardant in domestic and international markets is mainly aluminum hydroxide trihydrate (ATH), typically denoted as α-Al₂O₃·3H₂O. It appears as a crystalline or amorphous white powder. Its crystal structure consists of tightly packed base ions arranged in an AB double-layer form, with aluminum ions occupying all octahedral voids formed by the stacked 9s base ions.

The thermal dehydration and phase transitions of flame-retardant aluminum hydroxide are highly complex. When selecting aluminum hydroxide as a flame retardant, its quality indicators must be chosen based on the thermal decomposition temperature and processing temperature requirements of the polymer matrix material.

Modified flame-retardant aluminum hydroxide is one of the halogen-free flame retardants for synthetic materials. It possesses three major functions: flame retardancy, smoke suppression, and filling. It produces no secondary pollution during combustion. Not only does it exhibit excellent dispersibility in polymers, but it is also widely used in electrical appliances, wires, cables, daily necessities, building materials, transportation, and other plastic and rubber products.

The selection of aluminum hydroxide flame retardants requires attention to quality indicators. Aluminum hydroxide flame retardants offer advantages such as non-toxicity, excellent stability, and the absence of toxic gases at high temperatures. They reduce smoke and soot during plastic combustion, absorb heat during dehydration, and maintain low temperatures. Flame-retardant polyolefins containing 60% aluminum hydroxide can be used as construction materials and interior decoration materials for automobiles and ships.

The above covers the key quality indicators to consider when selecting flame-retardant aluminum hydroxide. We hope this information proves helpful.
