        WHA-203T Active Aluminum oxide Adsorbent
      
            
      
            
        
            1. Chemical formula: Al2O3.nH2O
            


            2. Properties and uses
            


            This product is the upgrading of WHA-203 product. It is γ-form active aluminum oxide with white color spherical particle. It is produced from the intermediate product as raw material, which is obtained by quick dehydration at high temperature. This product has higher adsorptive ability to the polar substance, and also can be regenerated through changing pressure and temperature. It can be used for the purification and decolorization of polyethylene, to improve the purity of polyethylene.
