Modified aluminum hydroxide

---

■ Brief Introduction

In order to improve its compatibility with organic interfaces and reduce or eliminate the embrittlement or performance degradation of organic materials caused by the addition of aluminum hydroxide, surface modification is necessary. The modified aluminum

Before aluminum hydroxide is surface-treated, it has many surface-active hydroxyl groups and certain polarity, making it difficult to disperse during downstream processing and thus affecting performance. To improve its compatibility with organic interfaces and reduce or eliminate the embrittlement or performance degradation of organic materials caused by the addition of aluminum hydroxide, surface modification of aluminum hydroxide is necessary. Modified aluminum hydroxide has a lower oil absorption and significantly improved dispersibility compared to unmodified powder.

■ Product Features

• With low oil absorption value and enhanced hydrophobicity

• Good dispersibility, less prone to agglomeration, and better anti-settling performance

• Modified aluminum hydroxide with increased cross-linking

• The cross section at the junction of groups is blurry, resulting in better dispersion
