詳細

詳細

Aluminum hydroxide is an inorganic compound widely used as an additive in electronic and polymeric applications due to its wide availability, corrosion resistance, light weightlessness, high melting point, good fire-retardant properties, and also its ability to release water of hydration at high temperatures (about 220 °C) to resist chemical bond breaking.[1][2]

アプリケーション

Aluminum hydroxide can be used as an inorganic filler in polymeric industries to produce high-voltage outdoor insulation materials (silicone rubber composites) to improve flame retardancy and tracking resistance properties. In the fabrication of glass fiber reinforced polymer (GFRP)- hybrid composites, aluminum hydroxide is used as a modifier to enhance the mechanical and fire-retardant properties of the composites.[2][3]

Aluminum hydroxide also finds application in ceramic and glass industries to prepare heat resistance materials due to its non-flammability and high melting point characteristics.[4][5]
