1.Product Information:
The activated alumina desiccant is a white, sperical porous material with the property of non-toxic, odorless, insoluble in water and ethanol. The particle size is uniform, the surface is smooth, the mechanical strengh is higf, the ability of moisture absorption is strong and the ball will not split after absorbing water.
