Product Overview

Activated Aluminum Hydroxide Ultrafine Powder is a premium surface-treated flame retardant filler designed for high-performance composite applications. Through advanced surface modification technology using silane or titanate coupling agents, this specialized aluminum hydroxide achieves superior compatibility with various polymer matrices.


The product features exceptionally fine particle size with narrow distribution, excellent whiteness, and remarkable room-temperature stability. Unlike conventional aluminum hydroxide fillers, our activated version significantly enhances the interfacial bonding between inorganic filler and organic resins, creating composites with outstanding comprehensive properties.
