Modified aluminum hydroxide ATH-1
Before surface treatment, aluminum hydroxide has a large number of surface active light groups with certain polarity, which makes it difficult to disperse and open during downstream processing, leading to performance issues. 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 chloroalumina will reduce its oil absorption and significantly improve its dispersibility compared to the powder.

Notes
If silicone rubber has requirements for improving its aging resistance (without yellowing after thermal aging), it is necessary to communicate with our sales personnel in advance and provide customized samples (phenylsilane containing silicone);
Before testing and using composite modified products, it is necessary to first compare the performance of a single treatment and the original powder, and analyze the differences between the two and the sample before determining the applicable composite treatment;
We can accept customized requirements for processing. If you have any requirements, please communicate with the business leader and R&D engineer.
