1. Product Features
Aluminum hydroxide (Al(OH)₃) is a white amphoteric powder with a relative molecular mass of 78; when heated to 200°C it begins to rapidly dehydrate, releasing a large amount of water. Our aluminum hydroxide flame retardant features ultra-fine particles, high purity, whiteness, fine particle size, and uniform particle distribution. The surface is fully modified with a silane coupling agent, giving good compatibility with polymer materials and almost no impact on material properties even at high addition levels.
