Aluminum hydroxide Molecular formula: Al (OH) 3 Aluminum hydroxide Molecular weight: 78

 

Aluminum hydroxide is the most widely used inorganic flame retardant, because of its low toxicity, smoke suppression, low corrosion and the price than the halogen, phosphorus system cheap. With the proper formulation, the materials can meet various testing requirements. Aluminum hydroxide is mainly used for processing temperature below 200 ℃ in the artificial rubber, thermosetting resins and thermoplastics. Aluminum hydroxide is a non-toxic, white to pale white powder, the relative density of 2.42, Mohs hardness of 3.0, when the temperature is heated to above 320 ℃, ATH loss of water loss of its quality 34.6%. The company's aluminum hydroxide flame retardant by the advanced surface treatment process, the degree of activation of 98 percent, and rubber, plastics and other materials compatibility, and greatly reduce the filling of the poor physical and mechanical properties.
