pseudo-boehmite
This product is a macroporous, medium-density pseudo-boehmite, featuring high purity, large pore volume, uniform pore size distribution, good fluidity and easy acid solubility.
This product features excellent formability, high strength and good wear resistance. It is widely used in the catalyst industry such as hydrocracking, residue oil hydrogenation and hydrofining, and can also serve as an important component of fine abrasives and high-temperature adhesives.
