■ 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 hydroxide has a lower oil absorption and significantly improved dispersibility compared to the unmodified powder.
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.
