Introduction
1.Property
Aluminum hydroxide, the chemical formula Al(OH)3, is a white powder with amphoteric properties of acid and alkali, with a relative molecular mass of 78. The product begins to rapidly dehydrate when heated to 200℃ and decomposes to produce a large amount of water. Because it has good flame retardant properties like magnesium hydroxide, it is one of the earliest used inorganic environmentally friendly flame retardants. The aluminum hydroxide flame retardant produced by our company has the characteristics of ultra-fine, high purity, whiteness, fine particle size, and uniform distribution. The surface is fully modified with silane coupling agent, and it has good compatibility with polymer materials, and it hardly affects the performance of the material when added in large amounts.
