Note: 1. In addition to the above series of products, our factory can produce alumina gel and activated alumina according to the special requirements of users to adapt to PE, PP, PTA and other devices. 2. The ball diameter of the above products is Φ1.0~2.5 except for GA-308, Φ5~7 by GA-309, and Φ3~5 by the rest, which can be produced according to the requirements of users. |
